System ports are unique identifiers in a multi-ASIC environment that
represent all the available ports in the system. Local ports on the
other hand, are unique only within the local ASIC.
Since system port to local port mapping is not part of the HW-SW
contract and since only single-ASIC configurations are currently
supported, set an explicit 1:1 mapping by configuring the Switch System
Port Record (SSPR) register.

An RX stall issue was seen on Lancer adapters, when RXQs are destroyed
while they are in an "out of buffer" state. This patch fixes this issue

HW issues were observed on Lancer adapters if IFACE filters
(flags, mac addrs etc) are enabled *before* creating RXQs. This patch
changes the driver design by enabling filters in be_open() --
instead of be_setup() -- after RXQs are created and buffers posted.
Two new wrapper functions, be_enable_if_filters() and
be_disable_if_filters() are introduced to enable/disable IFACE filters in
be_open()/be_close() respectively. In be_setup() the IFACE is now created
only with the RSS flag.

Intel Wired LAN Driver Updates 2015-08-05
This series contains updates to i40e, i40evf and e1000e.
Anjali adds support for x772 devices to i40e and i40evf. With the added
support, x772 supports offloading of the outer UDP transmit and receive
checksum for tunneled packets. Also supports evicting ATR filters in the
hardware, so update the driver with this new feature set.
Raanan provides several fixes for e1000e, first rectifies the Energy
Efficient Ethernet in Sx code so that it only applies to parts that
actually support EEE in Sx. Fix whitespace and moved ICH8 related define
to the proper context. Fixed the ASPM locking which was reported by

experience a large non-linear increment of the systime value when

Prior to this patch, rx buffer size for each rx queue
of an interface is configurable through dts bindings.
But for an interface, the first rx queue's rx buffer
size is always the usual MTU size (plus usual overhead)
and page size for the remaining rx queues (if they are
enabled by specifying a non-zero rx queue depth dts
binding of the corresponding interface). This patch
removes the rx buffer size configuration capability.

Generally an RX packet flows through the following objects:
Flow table --> TIR --> RQT --> RQ
Where:
- TIR stands for "Transport Interface Receive", defining the RSS and
LRO paramaters.
- RQT stands for "RQ Table", implementing the RSS indirection table.
- RQ stands for "Receive Queue"
For flows that do not need LRO, nor RSS, the driver made a shortcut to
the above RX flow by pointing to the RQ directly from the TIR, yielding
this flow:
Flow table --> TIR --> RQ
In this commit we remove this shortcut by "inserting" a single-RQ RQT
between the TIR and the RQ, i.e RX packets will reach the same RQ but
will go through an RQT of size 1, pointing to just a single RQ.
This way the RX traffic re-direction to/from the "Drop RQ" will be more
uniform (AKA "one flow"), as it will involve only RQTs re-direction and
no TIRs re-direction.

no need to do local_irq_save() around gfar_halt_nodisable().
lock_rx_qs()/unlock_tx_qs() are just obsoleted and potentially
buggy routines. The txlock is currently used in the driver only
to manage TX congestion, it has nothing to do with halting the
device. With these changes, the TX processing is stopped before
gfar_halt().
Compact gfar_halt() is used instead of gfar_halt_nodisable(),
as it disables Rx/TX DMA h/w blocks and the Rx/TX h/w queues.
gfar_start() re-enables all these blocks on resume. Enabling
the magic-packet mode remains the same, note that the RX block
is re-enabled just before entering sleep mode.
Add IRQF_NO_SUSPEND flag for the error interrupt line, to signal
that the interrupt line must remain active during sleep in order
to wake the system by magic packet (MAG) reception interrupt.
(On some systems the MAG interrupt did trigger w/o this flag
as well, but on others it didn't.)
Without these fixes, when suspended during fair Tx traffic the
interface occasionally failed to be woken up by magic packet.

The policy in the net driver is to attempt MCDI commands and
then handle any EPERM error codes appropriately when returned
by unprivileged functions.
The ethtool selftest contains some tests which are useful on
an unprivileged function, such as the event queue interrupt
tests, but other tests cannot be performed as the function
does not have the required permissions.
If a test returns -EPERM, act as though the test was not run

Ethernet Management Datagrams (EMADs) are Ethernet packets sent between
the host and the device in order to configure the available device registers.
Another use case is notifications sent from the device to the host,
letting it know about certain events, such as port up / down.
Add the ability to construct EMADs with provisions to construct and
parse the registers' payloads. Implement EMAD transaction layer
which is responsible for the reliable transmission of EMADs. Also, add
an infrastructure used by the switch driver to register for particular

With earlier configured value sufficient number of CQEs are not
being reserved for transmitted packets. Hence under heavy incoming
traffic load, receive notifications will take away most of the CQ
thus transmit notifications will be lost resulting in tx skbs not
being freed.
Finally SQ will be full and it will be stopped, watchdog timer
will kick in. After this fix receive notifications will not take
morethan half of CQ reserving the rest for transmit notifications.
Also changed CQ & SQ sizes from 16k to 4k.
This is also due to the receive notifications taking first half of
CQ under heavy load and time taken by NAPI to clear transmit notifications
will increase with higher queue sizes. Again results in SQ being stopped.

1) It requires additional instance of struct mlx5e_params on the

2) Sometimes we want to do additional operations (besides
just updating the priv parameters) while the netdev is stopped.

Normally the tilegx networking shim sends irqs to all the cores
to distribute the load of processing incoming-packet interrupts,
so that you can get to multiple Gb's of traffic inbound.
However, in nohz_full mode we don't want to interrupt the
nohz_full cores by default, so we limit the set of cores we use
to only the online housekeeping cores.
To make client code easier to read, we introduce a new nohz_full
accessor, housekeeping_cpumask(), which returns a pointer to the
housekeeping_mask if nohz_full is enabled, and otherwise returns
the cpu_possible_mask.

users who are interested in 802.1ad hardware acceleration should turn ON
the phv-bit private flag:
$ ethtool --set-priv-flags eth1 phv-bit on
Once the private flag is set, the device is ready for 802.1ad vlan
acceleration.
The user should also change the interface device features and turn on
"tx-vlan-stag-hw-insert" which is off by default:
$ ethtool -K eth1 tx-vlan-stag-hw-insert on
"phv-bit" private flag setting is available only for Physical

Renesas Ethernet AVB controller requires that all data are aligned on 4-byte
boundary. While it's easily achievable for the RX data with the help of
skb_reserve() (we even align on 128-byte boundary as recommended by the manual),
we can't do the same with the TX data, and it always comes unaligned from
the networking core. Originally we solved it an easy way, copying all packet
to a preallocated aligned buffer; however, it's enough to copy only up to
3 first bytes from each packet, doing the transfer using 2 TX descriptors
instead of just 1. Here's an implementation of the new TX algorithm that
significantly reduces the driver's memory requirements.

Add support for runtime PM to control this clock. Enable/disable this
clock using runtime PM, with open()/close() and mdio read()/write()
function triggering runtime PM operations. Since PM is optional, the
IPG clock is enabled at probe and is no longer modified by
fec_enet_clk_enable(), thus if PM is not enabled in the kernel, it is
guaranteed the clock is running when MDIO operations are performed.

A regular TX WQE execution involves two or more DMA reads -
one to fetch the WQE, and another one per WQE gather entry.
These DMA reads obviously increase the TX latency.
There are two mlx5 mechanisms to bypass these DMA reads:
1) Inline WQE
2) Blue Flame (BF)
An inline WQE contains a whole packet, thus saves the DMA read/s
of the regular WQE gather entry/s. Inline WQE support was already
added in the previous commit.
A BF WQE is written directly to the device I/O mapped memory, thus
enables saving the DMA read that fetches the WQE.
The BF WQE I/O write must be in cache line granularity, thus uses
the CPU write combining mechanism.
A BF WQE I/O write acts also as a TX doorbell for notifying the
device of new TX WQEs.
A BF WQE is written to the same I/O mapped address as the regular TX
doorbell, thus this address is being mapped twice - once by ioremap()
and once by io_mapping_map_wc().
While both mechanisms reduce the TX latency, they both consume more CPU
cycles than a regular WQE:
- A BF WQE must still be written to host memory, in addition to being
written directly to the device I/O mapped memory.
- An inline WQE involves copying the SKB data into it.
To handle this tradeoff, we introduce here a heuristic algorithm that
strives to avoid using these two mechanisms in case the TX queue is
being back-pressured by the device, and limit their usage rate otherwise.
An inline WQE will always be "Blue Flamed" (written directly to the
device I/O mapped memory) while a BF WQE may not be inlined (may contain
gather entries).
Preliminary testing using netperf UDP_RR shows that the latency goes down
from 17.5us to 16.9us, while the message rate (tested with pktgen) stays
the same.

Commit 8d88c6ebb3 ("net: bcmgenet: enable MoCA link state change
detection") added a fixed PHY link_update callback for MoCA PHYs when
registered using platform_data exclusively, this change is also
applicable to systems using Device Tree as their primary configuration
interface.
In order for this to work, move the link_update assignment into
bcmgenet_moca_phy_setup() where we know for sure that we are running on
a MoCA GENET instance, and do not override phydev->link since this is:
- properly taken care of by the PHY library by getting the link UP/DOWN
interrupts
- this now runs everytime we call bcmgenet_open(), so we need to
preserve whatever we detected before we went administratively DOWN and
then UP
- we need to make sure that MoCA PHYs start with a link DOWN during
probe in order to force a link transition to occur
To avoid a forward declaration, move bcmgenet_fixed_phy_link_update()
above its caller.

When a port is not attached, the FW requires a longer than usual time to
execute the SENSE_PORT command. In the command flow, the
wait_for_completion_timeout call used in mlx4_cmd_wait puts the kernel
thread into the uninterruptible state during this time. This, in turn,
due to the computation method, causes the CPU load average to increase.
Fix this by using wait_for_completion_interruptible_timeout() for the
SENSE_PORT command, which puts the thread in the interruptible state.
In this state, the thread does not contribute to the CPU load average.
Treat the interrupted case as if the SENSE_PORT command returned
port_type = NONE.

Intel Wired LAN Driver Updates 2015-07-23
This series contains updates to e1000e, igb, ixgbevf, i40e and i40evf.
Emil extends the reporting of the RSS key and hash table by adding support
for x550 VFs.
Jia-Ju Bai fixes a QoS issue in e1000e where the error handling lacked a
call to pm_qos_remove_request() to cleanup the QoS request made in
e1000_open().
Todd updates igb to report unsupported for ethtool coalesce settings
that are not supported. Also updated the driver to use the ARRAY_SIZE()
macro.
Carolyn fixes and refactors the dynamic ITR code for i40e and i40evf
which would never change dynamically. So update the switch() statement
to have a default case and switch on "new_latency_range" versus the
current ITR setting.
Shannon cleans up i40e code, where there were un-needed goto's. Also
clean up error status messages that were causing some confusion in
PHY and FCoE setup error reports.
Mitch updates the virtual channel interface to prepare for the x722 device
and other future devices, so that the VF driver can report what its
capable of supporting to the PF driver. Updates the i40evf driver to
handle resets like Core or EMP resets, where the device is reinitialized
and the VF will not get the same VSI.
Jesse updates the i40e and i40evf driver to use the kernel BIT() and
BIT_ULL() macros.

The most common type of reset that the VF will encounter is a PF reset
that cascades down into a VF reset for each VF. In this case, the VF
will always be assigned the same VSI and recovery is fairly simple.
However, in the case of 'bigger' resets, such as a Core or EMP reset,
when the device is reinitialized, it's probable that the VF will NOT get
the same VSI. When this happens, the VF will not be able to recover, as
it will continue to request resources for its original VSI.
Add an extra state to the admin queue state machine so that the driver
can re-request its configuration information at runtime. During reset
recovery, set this bit in the aq_required field, and fetch the (possibly
new) configuration information before attempting to bring the driver
back up. Since the driver doesn't know what kind of reset it has
encountered, this step is done even for a PF reset, but it doesn't hurt
anything - it just gets the same VSI back.

To prepare for the changes coming up in the X722 device and future
devices, the virtual channel interface has to change slightly. The VF
driver can now report what its capable of supporting, which then informs
the PF driver when it sends the configuration information back to the
VF.
A 1.1 VF driver on a 1.0 PF driver should not send its capabilities.
Likewise, a 1.1 PF driver controlling a 1.0 VF driver should not expect
or depend upon receiving the VF capabilities.
All other aspects of the API are unchanged.

This patch extends the reporting of the RSS key and hash table by
adding support for X550 VFs. The difference is that X550 VFs have

no need to query the PF.
The RSS key and indirection table are stored in the adapter structure
during the configuration of VFRSSRK and VFRETA which in turn can be
used in ethtool for reporting.
The logic for writing VFRETA is also changed to make sure that the
indirection table is reported correctly.
In addition this patch adds defines for the VFRETA entries and number
of VFRSSRK registers as well as some whitespace cleanups.

- Packets from a VF with pvid configured which were sent with a
different vlan were transmitted instead of being discarded.
- FCoE traffic might not recover after a failue while there's traffic
to another function.
In addition, this FW opens the door for the driver to implement several
new features; Specifically, this enhances the device's support for
encapsulated packets and will allow vxlan/geneve offloads to be added in
the future, as well as vlan filtering offload.

The driver is written as if it can adapt to a low memory situation allocating
less RX skbs and TX aligned buffers than the respective RX/TX ring sizes. In
reality though the driver would malfunction in this case. Stop being overly
smart and just fail in such situation -- this is achieved by moving the memory
allocation from ravb_ring_format() to ravb_ring_init().
We leave dma_map_single() calls in place but make their failure non-fatal
by marking the corresponding RX descriptors with zero data size which should
prevent DMA to an invalid addresses.

If the workaround to support cascaded multicast filters ("workaround_26807") is
enabled, the broadcast filter and individual multicast filters are not inserted
when in promiscuous or allmulti mode.
There is a race while inserting and removing filters when entering and leaving
promiscuous mode. When changing promiscuous state with cascaded multicast
filters, the old multicast filters are removed before inserting the new filters
to avoid duplicating packets; this can lead to dropped packets until all
filters have been inserted.
The efx_nic:mc_promisc flag is added to record the presence of a multicast
promiscuous filter; this gives a simple way to tell if the promiscuous state is
changing.

With the actual code, if a memory allocation error happens while

to the networking stack (in a SKB) and let in the Rx ring. This leads
to various kernel oops and crashes.
As a fix, this patch moves Rx descriptor refilling ahead of building

Intel Wired LAN Driver Updates 2015-07-17
This series contains updates to igb, ixgbe, ixgbevf, i40e, bnx2x,
freescale, siena and dp83640.
Jacob provides several patches to clarify the intended way to implement
both SIOCSHWTSTAMP and ethtool's get_ts_info(). It is okay to support
the specific filters in SIOCSHWTSTAMP by upscaling them to the generic
filters.
Alex Duyck provides a igb patch to pull the time stamp from the fragment
before it gets added to the skb, to avoid a possible issue in which the
fragment can possibly be less than IGB_RX_HDR_LEN due to the time stamp
being pulled after the copybreak check. Also provides a ixgbevf patch to
fold the ixgbevf_pull_tail() call into ixgbevf_add_rx_frag(), which gives
the advantage that the fragment does not have to be modified after it is
added to the skb.
Fan provides patches for ixgbe/ixgbevf to set the receive hash type
based on receive descriptor RSS type.
Todd provides a fix for igb where on check for link on any media other
than copper was not being detected since it was looking on the incorrect
PHY page (due to the page being used gets switched before the function
to check link gets executed).

We are currently doing a full PHY initialization and even starting the
pHY state machine during bcmgenet_mii_init() which is executed in the
driver's probe function. This is convenient to determine whether we can
attach to a proper PHY device but comes at the expense of spending up to
10ms per MDIO transactions (to reach the waitqueue timeout), which slows
things down.
This also creates a sitaution where we end-up attaching twice to the
PHY, which is not quite correct either.
Fix this by moving bcmgenet_mii_probe() into bcmgenet_open() and update
its error path accordingly.
Avoid printing the message "attached PHY at address 1 [...]" every time
we bring up/down the interface and remove this print since it duplicates
what the PHY driver already does for us.

Our internal GPHY might be powered off before we attempt scanning the
MDIO bus and bind a driver to it. The way we are currently determining
whether a PHY is internal or not is done *after* we have successfully
matched its driver. If the PHY is powered down, it will not respond to
the MDIO bus, so we will not be able to bind a driver to it.
Our Device Tree for GENET interfaces specifies a "phy-mode" value:
"internal" which tells if this internal uses an internal PHY or not.
If of_get_phy_mode() fails to parse the 'phy-mode' property, do an
additional manual lookup, and if we find "internal" set the
corresponding internal variable accordingly.
Replace all uses of phy_is_internal() with a check against
priv->internal_phy to avoid having to rely on whether or not
priv->phydev is set correctly.

workarounds because we do not yet have MDIO interrupts enabled.
phy_resume() takes care of re-apply our workarounds in case we need any,
and bcmgenet_power_up() does a PHY hardware reset, all of this is more
than enough to guarantee that the PHY operates correctly.

The comment in question is word-for-word copied from ixgbe, and clearly
has no meaning in freescale's driver. (it even says 'return an error'
when the code clearly does not). Remove the comment as it is obviously
incorrect and not applicable to the code as it is today.

First, dma_sync_single_for_cpu() shouldn't have been called in the first place
(it's a streaming DMA API), dma_unmap_single() should have been called instead.
Second, dma_unmap_single() call after handing the buffer to napi_gro_receive()
makes little sense. Moreover desc->dptr might not be valid at this point.

Intel Wired LAN Driver Updates 2015-07-14
This series contains updates to i40e and i40evf only.
Joe Stringer and Jesse Gross add a ndo_features_check function to ensure
that the i40e driver does not try to offload packets that exceed 80 bytes
in length.
Anjali adds additional stats to track flow director ATR and SB current
state and flow director flush count which will help the need for verbose
debug logs with respect to flow director. Also refines an error message
to avoid confusion, so that it indicates what may have really happened
when the init_shared_code() call possibly fails.
Pawel adds new fields to the capabilities structures to handle Flex-10
device/function capabilities which is needed to support Flex-10 configs.
Jesse improves the transmit performance by added a prefetch for the
next transmit descriptor to be used when we know there are more coming.
Mitch modifies i40evf driver to handle/allow an abundance of vectors.
Currently the driver only maps transmit and receive queues to a single
MSI-X vector per queue if there are exactly enough vectors for this, but
if we have too many vectors, it will fail and allocate queues to vectors
in a suboptimal manner. So change the condition check to allow for an
excess number of vectors and won't use the extras. Also update the
driver to just return success if the user attempts to set a port VLAN on
a VF that already has the same port VLAN configured, instead of going
through unnecessary filter removals & adds. Fix the MAC filters for VFs,
which were being programmed with 0 for the VLAN value when there was no
VLAN assigned. Instead, we must use -1 to indicate that no VLAN is in
use. Fix the VF disable code, which was not properly cleaning up the VF
and would leave the VF in an indeterminate state, so fix this by
notifying the VF and then call the normal VF reset routine. Fix the
logic in the driver so that MAC filters are added and removed correctly
and added a check for the driver's hardware MAC address so that this
filter does not get removed incorrectly.
Carolyn removes incorrect #ifdef's which should not have been added in
the first place and with the #ifdef's removed, make the necessary
changes in the driver to resolve compile errors.
Greg updates the admin queue command header defines.

The eTSEC h/w is capable of scatter/gather on the receive side
too if MAXFRM > MRBLR, when the allowed maximum Rx frame size
is set to be greater than the maximum Rx buffer size (MRBLR).
It's about time the driver makes use of this h/w capability,
by supporting fixed buffer sizes and Rx S/G.
The buffer size given to eTSEC for reception is fixed to
1536B (must be multiple of 64), which is the same default
buffer size as before, used to accommodate standard MTU
(1500B) size frames. As before, eTSEC can receive frames of
up to 9600B. Individual Rx buffers are mapped to page halves
(page size for eTSEC systems is 4KB). The skb is built around
the first buffer of a frame (using build_skb()). In case the
frame spans multiple buffers, the trailing buffers are added
as Rx fragments to the skb. The last buffer in frame is marked
by the L status flag. A mechanism is in place to reuse the pages
owned by the driver (for Rx) for subsequent receptions.
Supporting fixed size buffers allows the implementation of Rx S/G,
which in turn removes the memory pressure issues the driver had
before when MTU was set for jumbo frame reception.
Also, in most cases, the Rx path becomes faster due to Rx page
reusal, since the overhead of allocating new rx buffers is removed
from the fast path.

Use "ndev" instead of "dev", as the rx queue back pointer
to a net_device struct, to avoid name clashing with a
"struct device" reference. This prepares the addition of a
"struct device" back pointer to the rx queue structure.
Remove duplicated rxq registration in the process.
Move napi_gro_receive() outside gfar_process_frame().

There are several (long standing) problems about how the status
field of the rx buffer descriptor (rxbd) is currently handled on
the error path:
- too many unnecessary 16bit reads of the two halves of the rxbd
status field (32bit), also resulting in overuse of endianness
convesion macros;
- "bdp->status = RXBD_LARGE" makes no sense, since the "large"
flag is read only (only eTSEC can write it), and trying to clear
the other status bits is also error prone in this context
(most of the rx status bits are read only anyway).
This is fixed with a single 32bit read of the "status" field,
and then the appropriate 16bit shifting is applied to access
the various status bits or the rx frame length. Also corrected
the use of the RXBD_LARGE flag.
Additional fix:
"rx_over_errors" stat is incremented instead of "rx_crc_errors"
in case of RXBD_OVERRUN occurrence.

Use a more common consumer/ producer index design to improve
rx buffer allocation. Instead of allocating a single new buffer
(skb) on each iteration, bundle the allocation of several rx
buffers at a time. This also opens the path for further memory
optimizations.
Remove useless check of rxq->rfbptr, since this patch touches
rx pause frame handling code as well. rxq->rfbptr is always
initialized as part of Rx BD ring init.
Remove redundant (and misleading) 'amount_pull' parameter.

The i40e_add_pd_table_entry() routine is being modified to handle both
cases where a backing page is passed and where backing page is allocated
in i40e_add_pd_table_entry().
For PBLE resource management, it is more efficient for it to manage its
backing pages. For VF, PBLE backing page addresses will be send to PF
driver for PBLE resource.
The i40e_remove_pd_bp() is also modified to not free pre-allocated pages and
free only ones which were allocated in i40e_add_pd_table_entry().

During close, all of the MAC filters are cleared, so the driver would be
unable to receive unicast packets after being closed and reopened.
Add the adapter's "hardware" MAC address filter in open, not init. This
ensures that the correct filter is present each time.

Due to an inverted conditional, the driver was marking all of its MAC
filters for deletion every time set_rx_mode was called. Depending upon
the timing of the calls to set_rx_mode and the processing of the admin
queue, the driver would (accidentally) end up with a varying number of
functional filters.
Correct this logic so that MAC filters are added and removed correctly.
Add a check for the driver's "hardware" MAC address so that this filter
doesn't get removed incorrectly.
