Sara Sharon 5eae443eb5 iwlwifi: pcie: detect and workaround invalid write ptr behavior
In 9000 series A0 step the closed_rb_num is not wrapping around
properly. The queue is wrapping around as it should, so we can
W/A it by wrapping the closed_rb_num in the driver.
While at it, extend RX logging and add error handling of other
cases HW values may cause us to access invalid memory locations.
Add also a proper masking of vid value read from HW - this should
not have actual affect, but better to be on the safe side.

Chaya Rachel Ivgi fcb6b92a68 iwlwifi: mvm: update ucode status before stopping device
Leaving ucode_loaded to true after stop_device() has been called
is a recipe for problems. Flows that are not sync'ed with the
driver life cycle (like debugfs hooks and thermal hooks) must
check that the firmware is loaded before they interact with it.
Therefore we need to keep this variable updated with the real
status of the firmware.

Yuval Mintz b4149dc7e1 qed: Print additional HW attention info
This patch utilizes the attention infrastructure to log additional
information that relates only to specific HW blocks.
For some of those HW blocks, it also stops automatically disabling the
attention generation as the attention is considered benign and thus
should only be logged; No fear of it flooding the system.

HW is capable of generating attentnions for a multitude of reasons,
but current driver is enabling attention generation only for management
firmware [required for link notifications].

This patch enables almost all of the possible reasons for HW attentions,

attentions from that source [to prevent possible attention flood].
It also lays the infrastructure for additional exploration of the various

Moshe Lazer 0ba422410b net/mlx5: Fix global UAR mapping
Avoid double mapping of io mapped memory, Device page may be
mapped to non-cached(NC) or to write-combining(WC).
The code before this fix tries to map it both to WC and NC
contrary to what stated in Intel's software developer manual.

Here we remove the global WC mapping of all UARS
"dev->priv.bf_mapping", since UAR mapping should be decided
per UAR (e.g we want different mappings for EQs, CQs vs QPs).

Caller will now have to choose whether to map via
write-combining API or not.

mlx5e SQs will choose write-combining in order to perform
BlueFlame writes.

Alexandre Belloni 99f81afc13 phy: micrel: Disable auto negotiation on startup
Disable auto negotiation on init to properly detect an already plugged
cable at boot.

At boot, when the phy is started, it is in the PHY_UP state.
However, if a cable is plugged at boot, because auto negociation is already
enabled at the time we get the first interrupt, the phy is already running.
But the state machine then switches from PHY_UP to PHY_AN and calls
phy_start_aneg(). phy_start_aneg() will not do anything because aneg is
already enabled on the phy. It will then wait for a interrupt before going
further. This interrupt will never happen unless the cable is unplugged and
then replugged.

It was working properly before 321beec504 (net: phy: Use interrupts when
available in NOLINK state) because switching to NOLINK meant starting
polling the phy, even if IRQ were enabled.

With the VLAN filtering enabled, these tables work in conjunction with

Guillaume Nault edffc2178d ppp: lock ppp->flags in ppp_read() and ppp_poll()
ppp_read() and ppp_poll() can be called concurrently with ppp_ioctl().
In this case, ppp_ioctl() might call ppp_ccp_closed(), which may update
ppp->flags while ppp_read() or ppp_poll() is reading it.
The update done by ppp_ccp_closed() isn't atomic due to the bit mask
operation ('ppp->flags &= ~(SC_CCP_OPEN | SC_CCP_UP)'), so concurrent
readers might get transient values.
Reading incorrect ppp->flags may disturb the 'ppp->flags & SC_LOOP_TRAFFIC'
test in ppp_read() and ppp_poll(), which in turn can lead to improper
decision on whether the PPP unit file is ready for reading or not.

Since ppp_ccp_closed() is protected by the Rx and Tx locks (with
ppp_lock()), taking the Rx lock is enough for ppp_read() and ppp_poll()
to guarantee that ppp_ccp_closed() won't update ppp->flags
concurrently.

The same reasoning applies to ppp->n_channels. The 'n_channels' field
can also be written to concurrently by ppp_ioctl() (through
ppp_connect_channel() or ppp_disconnect_channel()). These writes aren't
atomic (simple increment/decrement), but are protected by both the Rx
and Tx locks (like in the ppp->flags case). So holding the Rx lock
before reading ppp->n_channels also prevents concurrent writes.

Ido Schimmel 558c2d5e52 mlxsw: spectrum: Store local port to module mapping during init
The port netdevs are each associated with a different local port number
in the device. These local ports are grouped into groups of 4 (e.g.
(1-4), (5-8)) called clusters. The cluster constitutes the one of two
possible modules they can be mapped to. This mapping is board-specific
and done by the device's firmware during init.

When splitting a port by 4, the device requires us to first unmap all
the ports in the cluster and then map each to a single lane in the module
associated with the port netdev used as the handle for the operation.
This means that two port netdevs will disappear, as only 100Gb/s (4
lanes) ports can be split and we are guaranteed to have two of these
((1, 3), (5, 7) etc.) in a cluster.

When unsplit occurs we need to reinstantiate the two original 100Gb/s
ports and map each to its origianl module. Therefore, during driver init
store the initial local port to module mapping, so it can be used later
during unsplitting.

Note that a by 2 split doesn't require us to store the mapping, as we
only need to reinstantiate one port whose module is known.

it needs to override the current VF MAC address.

2. The MAC address is zero.  The VF will use a random MAC address by default.
By storing this 0 MAC address in the VF structure, it will allow the VF
user to change the MAC address later using ndo_set_mac_address() when

Neil Horman a6522c0898 3c59x: mask LAST_FRAG bit from length field in ring
Recently, I fixed a bug in 3c59x:

commit 6e144419e4
Author: Neil Horman <nhorman@tuxdriver.com>
Date:   Wed Jan 13 12:43:54 2016 -0500

    3c59x: fix another page map/single unmap imbalance

Which correctly rebalanced dma mapping and unmapping types.  Unfortunately it
introduced a new bug which causes oopses on older systems.

When mapping dma regions, the last entry for a packet in the 3c59x tx ring
encodes a LAST_FRAG bit, which is encoded as the high order bit of the buffers
length field.  When it is unmapped the LAST_FRAG bit is cleared prior to being
passed to the unmap function.  Unfortunately the commit above fails to do that
masking.  It was missed in testing because the system on which I tested it had
an intel iommu, the driver for which ignores the size field, using only the DMA
address as the token to identify the mapping to be released.  However, on older
systems that rely on swiotlb (or other dma drivers that key off that length
field), not masking off that LAST_FRAG high order bit results in parsing a huge
size to be release, leading to all sorts of odd corruptions and the like.

Fix is easy, just mask the length with 0xFFF.  It should really be
&(LAST_FRAG-1), but 0xFFF is the style of the file, and I'd like to make this
fix minimal and correct before making it prettier.

Appies to the net tree cleanly.  All testing on both iommu and swiommu based
systems produce good results

Sara Sharon 94bb44813e iwlwifi: mvm: add RSS queues notification infrastructure
In multi rx queue HW, without execessive locking, there is no sync
between the ctrl path (default queue) and the rest of the rx queues.
This might cause issues on certain situations. For example, in case
a delBA was processed on a default queue but out of order packets
still wait for processing on the other queue.

The solution is to introduce internal messaging between the CTRL path
and the other rx queues.
The driver will send a message to the firmware, which will echo it to
all the requested queues. The message will be in order inside the queue.
This way we can avoid CTRL path and RSS queues races.

Add support for this messaging mechanism. As the firmware is agnostic to
the data sent, add internal representation of the data as well.
Although currently only delBA flow will use it, the internal representation
will enable generic use of this infrastructure for future uses.
Next patch will utilize this messaging mechanism for the reorder buffer
delBA flow.

Sara Sharon 77fe739554 iwlwifi: mvm: update rx_status with mactime flag
When forming IBSS, mac80211 scans in order to find an already
existing cell to join.
In case the scan does not find any existing cell a new IBSS
cell is formed.
When receiving the beacons of another IBSS cell we should
merge if the other IBSS cell's TSF is higher than ours.
However, currently iwlmvm does not set any timestamp flag in
rx_status so there is no valid rx timestamp to compare the
beacon's TSF to.
The reason for that is that TSF as indicated by the firmware
is at INA time, but up till now mac80211 expected the TSF at
the beginning or end of the MPDU.
Set the flag to the newly added RX_FLAG_MACTIME_PLCP_START flag.

Luca Coelho a339e918da iwlwifi: mvm: handle pass all scan reporting
The firmware doesn't send match found notifications when no matchsets
are passed.  This makes sense because if there are no matchsets,
nothing can be matched.  But the nl80211 API should report when there
are results available, even if no matchsets were passed.

To handle this, we can use the firmware's ITERATION_COMPLETE
reporting, which will send us notifications every time it completed a
scheduled scan iteration.  Then we can set a flag when we received
beacons and use that to report that results are available.

====================
1GbE Intel Wired LAN Driver Updates 2016-02-24

This series contains updates to e1000e, igb and igbvf.

Raanan provides updates for e1000e, first increases the ULP timer since it
now takes longer for the ULP exit to complete on Skylake.  Fixes the
configuration of the internal hardware PHY clock gating mechanism, which was
causing packet loss due to mis configuring.  Fixed additional ULP
configuration settings which were not being properly cleared after cable
connect in V-Pro capable systems.  Added support for more i219 devices.

Takuma Ueba provides a fix for I210 where IPv6 autoconf test sometimes
fails due to DAD NS for link-local is not transmitted.  To avoid this
issue, we need to wait until 1000BASE-T status register "Remote receiver
status OK".

Todd provides a patch to override EEPROM WoL settings for specific OEM
devices. Then renamed igb defines to be more generic, since the define
E1000_MRQC_ENABLE_RSS_4Q enables 4 and 8 queues depending on the part.

Roland Hii fixes an issue where only the half cycle time of less than or
equal to 70 millisecond uses the I210 clock output function.  His patch
adds additional conditions when half cycle time is equal to 125 or 250 or
500 millisecond to use the clock output function.

Alex Duyck adds support for generic transmit checksums for igb and igbvf.

Jon Maxwell fixes an issues where customer applications are registering
and un-registering multicast addresses every few seconds which is leading
to many "Link is up" messages in the logs as a result of the
netif_carrier_off(netdev) in igbvf_msix_other().  So remove the
link is up message when registering multicast addresses.

Corinna Vinschen provides a fix for when switching off VLAN offloading on
i350, the VLAN interface becomes unusable.

Stefan Assmann updates the driver to use ndo_stop() instead of
dev_close() when running ethtool offline self test.  Since dev_close()
causes IFF_UP to be cleared which will remove the interfaces routes
and some addresses.

v2: Dropped patches 6-10 in the original series.  Patch 6-7 added support
    for character device for AVB and based on community feedback, we do not
    want to do this.  Patches 8-10 provided fixes to the problematic code
    added in patches 6 & 7.  So all of them must go!

Simon Horman 0dfa61bba3 can: rcar: add gen[12] fallback compatibility strings
Add fallback compatibility string for R-Car Gen 1 and Gen2.

In the case of Renesas R-Car hardware we know that there are generations of
SoCs, e.g. Gen 1 and Gen 2. But beyond that its not clear what the
relationship between IP blocks might be. For example, I believe that
r8a7779 is older than r8a7778 but that doesn't imply that the latter is a
descendant of the former or vice versa.

We can, however, by examining the documentation and behaviour of the
hardware at run-time observe that the current driver implementation appears
to be compatible with the IP blocks on SoCs within a given generation.

For the above reasons and convenience when enabling new SoCs a
per-generation fallback compatibility string scheme being adopted for
drivers for Renesas SoCs.

Chun-Hao Lin f09cf4b783 r8169:fix "rtl_counters_cond == 1 (loop: 1000, delay: 10)" log spam.
There will be a log spam when there is no cable plugged. Please refer to
following links. https://bugzilla.kernel.org/show_bug.cgi?id=104351
https://bugzilla.kernel.org/show_bug.cgi?id=107421

This issue is caused by runtime power management. When there is no cable
plugged, the driver will be suspend (runtime suspend) by OS and NIC will be
put into the D3 state. During this time, if OS call rtl8169_get_stats64()
to dump tally counter, because NIC is in D3 state, the register value read
by driver will return all 0xff. This will let driver think tally counter
flag is not toggled and then sends the warning message "rtl_counters_cond
== 1 (loop: 1000, delay: 10)" to kernel log.

For fixing this issue, 1.add checking driver's pm runtime status in
rtl8169_get_stats64(). 2.dump tally counter before going runtime suspend
for counter accuracy in runtime suspend.

A bug was introduced in the merge commit b633353115 ("Merge
git://git.kernel.org/pub/scm/linux/kernel/git/davem/net")
The generic marvell_config_init (and therefore marvell_of_reg_init) is
not called anymore for the Marvell 88E1510 (in net-next).

This patch calls marvell_config_init and moves the specific init
function for the 88E1510 below the marvell_config_init function to avoid
adding a function predeclaration.

Hante Meuleman 19c8f421a6 brcmfmac: Increase nr of supported flowrings.
New generation devices have firmware which has more than 256 flowrings.
E.g. following debugging message comes from 14e4:4365 BCM4366:
[  194.606245] brcmfmac: brcmf_pcie_init_ringbuffers Nr of flowrings is 264

At various code places (related to flowrings) we were using u8 which
could lead to storing wrong number or infinite loops when indexing with
this type. This issue was quite easy to spot in brcmf_flowring_detach
where it led to infinite loop e.g. on failed initialization.

This patch switches code to proper types and increases the maximum
number of supported flowrings to 512.

Originally this change was sent in September 2015, but back it was
causing a regression on BCM43602 resulting in:
Unable to handle kernel NULL pointer dereference at virtual address ...

The reason for this regression was missing update (s/u8/u16) of struct
brcmf_flowring_ring. This problem was handled in 9f64df9 ("brcmfmac: Fix
bug in flowring management."). Starting with that it's safe to apply
this original patch as it doesn't cause a regression anymore.

This patch fixes an infinite loop on BCM4366 which is supported since
4.4 so it makes sense to apply it to stable 4.4+.

This avoids the problem by adding a separate Kconfig symbol named

This is the same trick that BNX2X does for VXLAN support, and
is similar to how I40E handles both.

Stefan Assmann 46eafa59e1 igb: call ndo_stop() instead of dev_close() when running offline selftest
Calling dev_close() causes IFF_UP to be cleared which will remove the
interfaces routes and some addresses. That's probably not what the user
intended when running the offline selftest. Besides this does not happen
if the interface is brought down before the test, so the current
behaviour is inconsistent.
Instead call the net_device_ops ndo_stop function directly and avoid
touching IFF_UP at all.

Corinna Vinschen 030f9f5264 igb: Fix VLAN tag stripping on Intel i350
Problem: When switching off VLAN offloading on an i350, the VLAN
interface gets unusable.  For testing, set up a VLAN on an i350
and some remote machine, e.g.:

  $ ip link add link eth0 name eth0.42 type vlan id 42
  $ ip addr add 192.168.42.1/24 dev eth0.42
  $ ip link set dev eth0.42 up

Offloading is switched on by default:

  $ ethtool -k eth0 | grep vlan-offload
  rx-vlan-offload: on
  tx-vlan-offload: on

  $ ping -c 3 -I eth0.42 192.168.42.2
  [...works as usual...]

Now switch off VLAN offloading and try again:

  $ ethtool -K eth0 rxvlan off
  Actual changes:
  rx-vlan-offload: off
  tx-vlan-offload: off [requested on]
  $ ping -c 3 -I eth0.42 192.168.42.2
  PING 192.168.42.2 (192.168.42.2) from 192.168.42.1 eth0.42: 56(84) bytes of da
ta.

  --- 192.168.42.2 ping statistics ---
  3 packets transmitted, 0 received, 100% packet loss, time 1999ms

I can only reproduce it on an i350, the above works fine on a 82580.

While inspecting the igb source, I came across the code in igb_set_vmolr
which sets the E1000_VMOLR_STRVLAN/E1000_DVMOLR_STRVLAN flags once and
for all, and in all of the igb code there's no other place where the
STRVLAN is set or cleared.  Thus, VLAN stripping is enabled in igb
unconditionally, independently of the offloading setting.

I compared that to the latest Intel igb-5.3.3.5 driver from
http://sourceforge.net/projects/e1000/ which in fact sets and clears the
STRVLAN flag independently from igb_set_vmolr in its own function
igb_set_vf_vlan_strip, depending on the vlan settings.

So I included the STRVLAN handling from the igb-5.3.3.5 driver into our
current igb driver and tested the above scenario again.  This time ping
still works after switching off VLAN offloading.

Tested on i350, with and without addtional VFs, as well as on 82580
successfully.

Jon Maxwell cc54a59ae6 igbvf: remove "link is Up" message when registering mcast address
A similar issue was addressed a few years ago in the following thread:

http://www.spinics.net/lists/netdev/msg245877.html

At that time there were concerns that removing this statement may cause other
side effects. However the submitter addressed those concerns. But the dialogue
went cold. We have a new case where a customers application is registering and
un-registering multicast addresses every few seconds. This is leading to many
"Link is Up" messages in the logs as a result of the
"netif_carrier_off(netdev)" statement called by igbvf_msix_other(). Also on
some kernels it is interfering with the bonding driver causing it to failover
and subsequently affecting connectivity.

The Sourgeforge driver does not make this call and is therefore not affected.
If there were any side effects I would expect that driver to also be affected.
I have tested re-loading the igbvf driver and downing the adapter with the PF
entity on the host where the VM has this patch. When I bring it back up again
connectivity is restored as expected. Therefore I request that this patch gets
submitted.

Alexander Duyck ea6ce6024f igbvf: Add support for generic Tx checksums
This patch adds support for generic Tx checksums to the igbvf driver.  It
turns out this is actually pretty easy after going over the datasheet as we
were doing a number of steps we didn't need to.

In order to perform a Tx checksum for an L4 header we need to fill in the
following fields in the Tx descriptor:
  MACLEN (maximum of 127), retrieved from:
		skb_network_offset()
  IPLEN  (maximum of 511), retrieved from:
		skb_checksum_start_offset() - skb_network_offset()
  TUCMD.L4T indicates offset and if checksum or crc32c, based on:
		skb->csum_offset

The added advantage to doing this is that we can support inner checksum
offloads for tunnels and MPLS while still being able to transparently
insert VLAN tags.

I also took the opportunity to clean-up many of the feature flag
configuration bits to make them a bit more consistent between drivers.  In
the case of the VF drivers this meant adding support for SCTP CRCs, and
inner checksum offloads for MPLS and various tunnel types.

Roland Hii 569f3b3d4e igb: add conditions for I210 to generate periodic clock output
In general case the maximum supported half cycle time of the synchronized
output clock is 70msec. Slower half cycle time than 70msec can be
programmed also as long as the output clock is synchronized to whole
seconds, useful specifically for generating a 1Hz clock.

Permitted values for the clock half cycle time are: 125,000,000 decimal,
250,000,000 decimal and 500,000,000 decimal (equals to 125msec, 250msec
and 500msec respectively).

Before this patch, only the half cycle time of less than or equal to 70msec
uses the I210 clock output function. This patch adds additional conditions
when half cycle time is equal to 125msec or 250msec or 500msec to use
clock output function.

Under other conditions, interrupt driven target time output events method
is still used to generate the desired clock output.

ajit.khaparde@broadcom.com 127bfce541 be2net: Fix a UE caused by passing large frames to the ASIC
In QnQ configurations like Flex-10 where the VLANs are inserted by the
ASIC, on rare occasions the HW is encountering a scenario where the
final frame length ends to be greater than what the ASIC can support.

This is because when the TXULP pulls the TX WRB to check the length
of the frame to be transmitted it also adds the size of VLANs to be
inserted by the HW to the length of the frame indicated in the WRB,
which in some cases fails the range check.  This causes a UE.

Avoid this by trimming the skb length to accommodate the VLAN insertion.

was always 1.

So far each channel had a single TXQ, Now each channel has a
TXQ per TC (Traffic Class).

Added en_dcbnl.c which implements the set/get DCBNL IEEE ETS,
set/get dcbx and registers the mlx5e dcbnl ops.

We still use the kernel's default TXQ selection method to select the
channel to transmit through but now we use our own method to select
the TXQ inside the channel based on VLAN priority.

In mlx5, as opposed to mlx4, tc group N gets lower priority than
tc group N+1.

Eliad Peller 1ad4f639cc iwlwifi: mvm: move TX PN assignment for TKIP to the driver
If protocol offloading is configured, the fw might generate some
frames (e.g. arp response) on its own during d3/d0i3.

On d3/d0i3 exit the driver queries the updated PN (if relevant),
and updates its keys (for the d0i3 case, this is done by
iwl_mvm_d0i3_exit_work(), which is scheduled on d0i3 exit)

While in d0i3, iwlmvm defers tx frames until d0i3 exit, and
then continues their processing.

This is problematic with TKIP, since the frame's PN has already
been set at this stage (in contrast to CCMP, where the PN is
being set only later on), so both the frame's PN and the upcoming
PN update (from d0i3 exit work) might be wrong.

Fix it by moving the TX PN assignment (for TKIP) to the driver,
similarly to CCMP.

Lior David 34d505193b cfg80211: basic support for PBSS network type
PBSS (Personal Basic Service Set) is a new BSS type for DMG
networks. It is similar to infrastructure BSS, having an AP-like
entity called PCP (PBSS Control Point), but it has few differences.
PBSS support is mandatory for 11ad devices.

Add support for PBSS by introducing a new PBSS flag attribute.
The PBSS flag is used in the START_AP command to request starting
a PCP instead of an AP, and in the CONNECT command to request
connecting to a PCP instead of an AP.

Michael Chan fbb0fa8b48 bnxt_en: Fix zero padding of tx push data.
The arithmetic to zero pad the last 64-bit word in the push buffer is not
correct.

1. It should be pdata + length to get to the end.
2. 'pdata' is void pointer and passing it to PTR_ALIGN() will cast the
aligned pointer to void.  Pass 'end' which is u64 pointer to PTR_ALIGN()
instead so that the aligned pointer - 1 is the last 64-bit pointer to data.

Some DSA drivers may or may not support multiple software bridges on top

It is more convenient for them to access the bridge's net_device for

Removing the need to craft and access a bitmask also simplifies the

This patch changes the signature of bridge related functions, update DSA
drivers, and removes dsa_slave_br_port_mask.

Robert Jarzmik b5a099c67a net: ethernet: davicom: fix devicetree irq resource
The dm9000 driver doesn't work in at least one device-tree
configuration, spitting an error message on irq resource :
[    1.062495] dm9000 8000000.ethernet: insufficient resources
[    1.068439] dm9000 8000000.ethernet: not found (-2).
[    1.073451] dm9000: probe of 8000000.ethernet failed with error -2

The reason behind is that the interrupt might be provided by a gpio
controller, not probed when dm9000 is probed, and needing the probe
deferral mechanism to apply.

Currently, the interrupt is directly taken from resources. This patch
changes this to use the more generic platform_get_irq(), which handles
the deferral.

Moreover, since commit Fixes: 7085a7401b ("drivers: platform: parse
IRQ flags from resources"), the interrupt trigger flags are honored in
platform_get_irq(), so remove the needless code in dm9000.

Alexander Duyck 6ceb31ca5f VXLAN: Support outer IPv4 Tx checksums by default
This change makes it so that if UDP CSUM is not specified we will default
to enabling it.  The main motivation behind this is the fact that with the
use of outer checksum we can greatly improve the performance for VXLAN
tunnels on devices that don't know how to parse tunnel headers.

Karicheri, Muralidharan 0632448134 net: netcp: rework the code for get/set sw_data in dma desc
SW data field in descriptor can be used by software to hold private
data for the driver. As there are 4 words available for this purpose,
use separate macros to place it or retrieve the same to/from
descriptors. Also do type cast of data types accordingly.

Karicheri, Muralidharan b1cb86ae0e soc: ti: knav_dma: rename pad in struct knav_dma_desc to sw_data
Rename the pad to sw_data as per description of this field in the hardware
spec(refer sprugr9 from www.ti.com). Latest version of the document is
at http://www.ti.com/lit/ug/sprugr9h/sprugr9h.pdf and section 3.1
Host Packet Descriptor describes this field.

Define and use a constant for the size of sw_data field similar to
other fields in the struct for desc and document the sw_data field
in the header. As the sw_data is not touched by hw, it's type can be
changed to u32.

Rename the helpers to match with the updated dma desc field sw_data.

Karicheri, Muralidharan 9ecfe875c4 net: ti: netcp: restore get/set_pad_info() functionality
The commit 8990777914 ("netcp: try to reduce type confusion in
descriptors") introduces a regression in Kernel 4.5-rc1 and it breaks
get/set_pad_info() functionality.

The TI NETCP driver uses pad0 and pad1 fields of knav_dma_desc to
store DMA/MEM buffer pointer and buffer size respectively. And in both
cases for Keystone 2 the pointer type size is 32 bit regardless of
LAPE enabled or not, because CONFIG_ARCH_DMA_ADDR_T_64BIT originally
is not expected to be defined.

Unfortunately, above commit changed buffer's pointers save/restore
code (get/set_pad_info()) and added intermediate conversation to u64
which works incorrectly on 32bit Keystone 2 and causes TI NETCP driver
crash in RX/TX path due to "Unable to handle kernel NULL pointer"
exception. This issue was reported and discussed in [1].

Hence, fix it by partially reverting above commit and restoring
get/set_pad_info() functionality as it was before.

Gerhard Uttenthaler 90cfde4658 can: ems_usb: Fix possible tx overflow
This patch fixes the problem that more CAN messages could be sent to the
interface as could be send on the CAN bus. This was more likely for slow baud
rates. The sleeping _start_xmit was woken up in the _write_bulk_callback. Under
heavy TX load this produced another bulk transfer without checking the
free_slots variable and hence caused the overflow in the interface.
