Move the counter for non-AMPDU frames to mvm. It is needed
for the drain flow which happens once the ieee80211_sta has
been freed, so keeping it in iwl_mvm_sta which is embed into
ieee80211_sta is not a good idea.
Also, since its purpose it to remove the STA in the fw only
after all the frames for this station have exited the shared
Tx queues, we need to decrement it in the reclaim flow. This
flow can happen after ieee80211_sta has been removed, which
means that we have no iwl_mvm_sta there. So we can't know
what is the vif type. Hence, we know audit these frames for
all the vif types.
In order to avoid spawning sta_drained_wk all the time, we
now check that we are in a flow in which draining might
happen - only when mvmsta is NULL. This is better than
previous code that would spawn sta_drained_wk all the time
in AP mode.

GENERIC_GPIO now synonymous with GPIOLIB. There are no longer any valid
cases for enableing GENERIC_GPIO without GPIOLIB, even though it is
possible to do so which has been causing confusion and breakage. This
branch does the work to completely eliminate GENERIC_GPIO.
However, it is not trivial to just create a branch to remove it. Over
the course of the v3.9 cycle more code referencing GENERIC_GPIO has been
added to linux-next that conflicts with this branch. The following must
be done to resolve the conflicts when merging this branch into mainline:
* "git grep CONFIG_GENERIC_GPIO" should return 0 hits. Matches should be
replaced with CONFIG_GPIOLIB
* "git grep '\bGENERIC_GPIO\b'" should return 1 hit in the Chinese
documentation.
* Selectors of GENERIC_GPIO should be turned into selectors of GPIOLIB
* definitions of the option in architecture Kconfig code should be deleted.
Stephen has 3 merge fixup patches[1] that do the above. They are currently
applicable on mainline as of May 2nd.

This can be readily reproduced when putting the XO-4 in a loop where
it goes to sleep due to inactivity, but then wakes up due to an
incoming ping. The error is hit within an hour or two.
This issue happens when an interrupt comes in early while host sleep
is still activated. Driver handles this case by auto cancelling host
sleep. However is_suspended flag is still set which prevents any cmd
or data from being sent to firmware. Fix it by clearing is_suspended
flag in this path.

When a reset or a channel-change happens, for managed mode,
the HW beacon timers have to be programmed after the TSF has

Jake reported that since commit 1672c0e319
"mac80211: start auth/assoc timeout on frame status", he is unable to
connect to his AP, which is configured to use passive channel.
After switch to passive channel 4965 firmware drops any TX packet until
it receives beacon. Before commit 1672c0e3 we waited on channel and
retransmit packet after 200ms, that makes we receive beacon on the
meantime and association process succeed. New mac80211 behaviour cause
that any ASSOC frame fail immediately on iwl4965 and we can not
associate.
This patch restore old mac80211 behaviour for iwl4965, by removing
IEEE80211_HW_REPORTS_TX_ACK_STATUS feature. This feature will be
added again to iwl4965 driver, when different, more complex
workaround for this firmware issue, will be added to the driver.

Add handling of rx descriptor underflow. This fixes a fault that could
happen on slow machines, where data is received faster than the CPU can
handle. In such a case the device will use up all rx descriptors and
refuse to send any more data before confirming that it is ok. This
patch enables necessary interrupt to discover such a situation and will
handle them by dropping everything in the ring buffer.

The driver and firmware sync up through SYNC messages, and the
firmware's affirmative reply to these SYNC messages appears to be the
"Reset" indication received via the status interrupt endpoint. Thus the
driver needs the status interrupt endpoint always active so that the
Reset indication can be received even if the netdev is closed, which is
the case right after device insertion.
If the Reset indication is not received by the driver, it continues
sending SYNC messages to the firmware, which crashes about 10 seconds
later and the device stops responding.

Some drivers (sierra_net) need the status interrupt URB
active even when the device is closed, because they receive
custom indications from firmware. Add functions to refcount
the status interrupt URB submit/kill operation so that
sub-drivers and the generic driver don't fight over whether
the status interrupt URB is active or not.
A sub-driver can call usbnet_status_start() at any time, but
the URB is only submitted the first time the function is
called. Likewise, when the sub-driver is done with the URB,
it calls usbnet_status_stop() but the URB is only killed when
all users have stopped it. The URB is still killed and
re-submitted for suspend/resume, as before, with the same
refcount it had at suspend.

Some ancient pHyp versions used to create a 8 bytes local-mac-address
property in the device-tree instead of a 6 bytes one for veth.
The Linux driver code to deal with that is an insane hack which also
happens to break with some choices of MAC addresses in qemu by testing
for a bit in the address rather than just looking at the size of the
property.

After recent 86a9bad3 (net: vlan: add protocol argument to packet
tagging functions) my sky2 started to crash on receive of tagged
frames, with backtrace similar to
#CRASH!!!
vlan_do_receive
__netif_receive_skb_core
__netif_receive_skb
netif_receive_skb
sky2_poll
...
__net_rx_action
__do_softirq
The problem turned out to be:
1) sky2 copies small packets from ring on RX, and in its
receive_copy() skb header is copied manually field, by field, and
only for some fields;
2) 86a9bad3 added skb->vlan_proto, which vlan_untag() or
__vlan_hwaccel_put_tag() set, and which is later used in
vlan_do_receive().
That patch updated copy_skb_header() for newly introduced
skb->vlan_proto, but overlooked the need to also copy it in sky2's
receive_copy().
Because of 2, we have the following scenario:
- frame is received and tagged in a ring, by sky2_rx_tag(). Both
skb->vlan_proto and skb->vlan_tci are set;
- later skb is decided to be copied, but skb->vlan_proto is
forgotten and becomes 0.
- in the beginning of vlan_do_receive() we call
__be16 vlan_proto = skb->vlan_proto;
vlan_dev = vlan_find_dev(skb->dev, vlan_proto, vlan_id);
which eventually invokes
vlan_proto_idx(vlan_proto)
and that routine BUGs for everything except ETH_P_8021Q and
ETH_P_8021AD.
Oops.
Fix it.
P.S.
Stephen, I wonder, why copy_skb_header() is not used in
sky2.c::receive_copy() ? Problems, where receive_copy was updated field
by field showed several times already, e.g.
3f42941b (sky2: propogate rx hash when packet is copied)
e072b3fa (sky2: fix receive length error in mixed non-VLAN/VLAN traffic)

...
It is easily reproducable by setting an MTU of 512 e. g. and sending
something like
ping -s 1472 -c 1 -M do $SELF
from another box.
And this is because the rx->ax_skb is freed on error, but rx->ax_skb
is not reset, and the size is not reset to zero in this case.
And since the skb is added again to the usbnet->done skb queue it is
accessing already freed memory, resulting in the BUG when freeing a
2nd time. I therefore think the value 0x0000004000000001 show in the
trace is more or less random data.

Pull i2c changes from Wolfram Sang:
- an arbitration driver. While the driver is quite simple, it caused
discussion if we need additional arbitration on top of the one
specified in the I2C standard. Conclusion is that I accept a few
generic mechanisms, but not very specific ones.
- the core lost the detach_adapter() call. It has no users anymore and
was in the way for other cleanups. attach_adapter() is sadly still
there since there are users waiting to be converted.
- the core gained a bus recovery infrastructure. I2C defines a way to
recover if the data line is stalled. This mechanism is now in the
core and drivers can now pass some data to make use of it.

In CPSW NAPI, after processing all interrupts IRQ is enabled and then book
keeping irq_enabled is updated. In random cases when a packet is transmitted
or received between processing packets and IRQ enabled, then just after
enabled IRQ and before irq_enabled is updated, ISR is called so IRQs are
not disabled as irq_enabled is still false and CPU gets locked in CPSW ISR.
By changing the sequence as update the irq_enabled and then enable IRQ
fixes the issue. This issue is not captured always as it is a timing issue
whether Tx or Rx IRQ is invoked between packet processing and enable IRQ.

This patch only changes some names to avoid confusion.
In this patch we have:
MAX_SKB_SLOTS_DEFAULT -> FATAL_SKB_SLOTS_DEFAULT
max_skb_slots -> fatal_skb_slots
#define XEN_NETBK_LEGACY_SLOTS_MAX XEN_NETIF_NR_SLOTS_MIN
The fatal_skb_slots is the threshold to determine whether a packet is
malicious.
XEN_NETBK_LEGACY_SLOTS_MAX is the maximum slots a valid packet can have at
this point. It is defined to be XEN_NETIF_NR_SLOTS_MIN because that's
guaranteed to be supported by all backends.

The Tilera hypervisor shipped in releases up through MDE 4.1 launches
the client operating system (i.e. Linux) at privilege level 1 (PL1).
Starting with MDE 4.2, as part of the work to enable KVM, the
Tilera hypervisor launches Linux at PL2 instead.
This commit makes the KERNEL_PL option default to 2 for tilegx, while
still saying at 1 for tilepro, which doesn't have an updated hypervisor.
It also explains how and when you might want to choose another value.
In addition, we change a small buglet in the on-chip Ethernet driver,
where we were failing to use the KERNEL_PL constant in an API call.
To make the transition cleaner, this change also provides the updated
hv_init() API for the new hypervisor that supports announcing Linux's
compiled-in PL, so the hypervisor can generate a suitable error in the
case of a mismatched hypervisor and Linux binary.

Here is a collection of fixes (and some intermixed cleanups) that were
considered less important and thus not included in the later parts of
the 3.9-rc cycle.
It's a bit all over the map, contents wise. A series of ux500 fixes
and cleanups, a bunch of various fixes for OMAP and tegra, and some for
Freescale i.MX and even Qualcomm MSM.
Note that there's also a patch on this branch to globally turn off
-Wmaybe-uninitialized when building with -Os. It's been posted several
times by Arnd and no dissent was raised, but nobody seemed interested
to pick it up. So here it is, as the topmost patch.

is generated as the irq_enabled is not initialized for the primary interface
and in probe it is initialized for the second interface. This patch moves
irq_enabled initialization from second interface to primary interface.

The venerable 3c509 driver only sets its device parent in one case, the ISAPnP one.
It does this with the SET_NETDEV_DEV function. It should register with the device
hierarchy in two additional cases: standard (non-PnP) ISA and EISA.
- Currently they appear here:
/sys/devices/virtual/net/eth0 (standard ISA)
/sys/devices/virtual/net/eth1 (EISA)
- Rather, they should instead be here:
/sys/devices/isa/3c509.0/net/eth0 (standard ISA)
/sys/devices/pci0000:00/0000:00:07.0/00:04/net/eth1 (EISA)
Tested on ISA and EISA boards.

Fixed: warning: cast from pointer to integer of different size
The Hyper-V hosts always use 64 bit request id. The guests can have 32 or 64
bit pointers which equal to the ulong type size. So we cast it to ulong type.
And, assigning 32bit integer to 64 bit variable works fine.
The VMBus returns the same id in the completion packet. But the value has no
effect on the host side.

Pegasus driver used single callback for sync and async control URBs.
Special flags were employed to distinguish between both, but due to flawed
logic it didn't always work. As a result of this change
[get|set]_registers() are now much simpler. Async write is also leaner
and does not use single, statically allocated memory for usb_ctrlrequest,
which is another potential race when asynchronously submitting URBs.

it prudent to try and push these into net at this time. I have CC'd

The 2 patches are:
e1000e: fix numeric overflow in phc settime method
ixgbe: fix EICR write in ixgbe_msix_other
Richard provides a fix for e1000e by using a helper function from time.h
to resolve a unintended overflow in the PTP settime function.
Bruce provides a fix to wait for NAPI to be done with the current context
after disabling interrupts and then disable NAPI when the interface
is going down. This fixes a possible "unable to handle kernel paging
request" panic in net-next.
Andi Kleen provides a patch for igb to use mdelay instead of udelay
when we needed 100000us.
Jacob provides a fix for ixgbe to simply mask the lower 16bits off so that
ixgbe_msix_other does not write them in the EICR, which causes them to
remain high and be properly handled by the clean_rings interrupt routine
as normal.
Emil cleans up the logic in ixgbe_setup_loopback_test() to only access
registers applicable to the MAC type. In addition, removes majority
of the AUTOC register reads by using a cached value instead to avoid
writing corrupted values to AUTOC due to bad FW. Emil also add support
for disabling link during boot time. Lastly, he provides a patch which
adds the MAC type to the version in ethtool_regs which will make it
easier to check the MAC type when dumping registers with ethtool.
There is a separate ethtool tool patch which is dependent upon Emil's
last patch of the series to add the MAC type to the version in
ethtool_regs, which will be sent separately.

Add support to ndo_set_vf_vlan in the driver. Once this call is used the vport
is considered to be in VST mode. In this mode, the PPF driver configures
Ethernet QPs created by this VF to use this vlan id and priority. Currently
RoCE isn't supported on that mode.
The special values of VID=4095 or VID=0,UP=0 are considered as VGT.

This patch add struct mlx4_vport_state where all the parameters related
to management of VFs port (virtual ports of the NIC eswitch) are kept.
The driver keeps an administrative and operational copy of the settings.
The current administrative copy becomes operational on the event of probing
a VF either on a VM or on the host.

Add reference counting to the driver MAC registeration code. This would
be needed for cases where a mac is registered from more than once, e.g
when both the host and the VM driver register the same mac, the host
for mac spoof protection purposes and the VM for its regular needs.
