====================
Mellanox mlx5 core driver updates 2016-08-20

This series contains several low level and API updates for mlx5 core
commands interface and mlx5_ifc.h to be shared as base code for net-next and
rdma mlx5 4.9 submissions.

From Saeed, ten patches that refactors old layouts of firmware commands which
were manually generated before we introduced the mlx5_ifc, now all of the firmware
commands inbox/outbox layouts moved to use mlx5_ifc and we remove the old
manually generated structures.  Plus to those ten patches, we add two patches
that unifies mlx5 commands execution interface and improve the driver log messages
in that area.

From Hadar and Ilya, added the needed hardware bits and infrastructure for
minimum inline headers setting and encap/decap commands and capabilities,
needed for E-Switch offloads.

This series applies on top latest net-next and rdma/master, and smoothly merges with
the latest "Mellanox 100G mlx5 fixes 2016-08-16" series already applied into net branch.

ce52c74457 net: ethernet: ti: cpsw: add ethtool channels support
These ops allow to control number of channels driver is allowed to
work with at cpdma level. The maximum number of channels is 8 for
rx and 8 for tx. In dual_emac mode the h/w channels are shared
between two interfaces and changing number on one interface changes
number of channels on another.

How many channels are supported and enabled:
$ ethtool -l ethX

Change number of channels (up to 8)
$ ethtool -L ethX rx 6 tx 6

Per-channel statistic:
$ ethtool -S ethX

e05107e6b7 net: ethernet: ti: cpsw: add multi queue support
The cpsw h/w supports up to 8 tx and 8 rx channels. This patch adds
multi-queue support to the driver only, shaper configuration will
be added with separate patch series. Default shaper mode, as
before, priority mode, but with corrected priority order, 0 - is
highest priority, 7 - lowest.

The poll function handles all unprocessed channels, till all of
them are free, beginning from hi priority channel.

In dual_emac mode the channels are shared between two network devices,
as it's with single-queue default mode.

The statistic for every channel can be read with:
$ ethtool -S ethX

080d5c5ac8 net: ethernet: ti: davinci_cpdma: fix locking while ctrl_stop
The interrupts shouldn't be disabled while receiving skb, but while
ctrl_stop, the channels are stopped and all remaining packets are
handled with netif_receive_skb(), it can cause WARN_ONCE when ctrl
is stopping while not all packets were handled with NAPIs:

lock_irq_save
    cpdma_ctlr_stop
       cpdma_chan_top
           __cpdma_chan_free
               cpsw_rx_handler
                   netif_receive_skb

So, split locking while ctrl stop thus interrupts are still
enabled while skbs handling. It can cause WARN_ONCE in rare
cases when ctrl is stopping while not all packets were handled
with NAPIs.

Tx channels share same pool of descriptors. Thus one channel can
block another if pool is emptied by one. But, the shaper should
decide which channel is allowed to send packets. To avoid such
impact of one channel on another, let every channel to have its
own piece of pool.

b0bccb69eb qed: Change locking scheme for VF channel
Each VF employees a lock that's supposed to serialize its usage of the
HW channel for communication with its PF, but the critical section is
ill-defined:

  - VFs currently release the lock whenever the PF response arrives,
    prior to actually processing the reply buffer [which was also supposed
    to have been protected by same lock].

  - The lock would be released on first response, ignoring the possibilty
    the sw flow isn't over [as might be the case of the acquisition flow].
    As a result, the flow would run unprotected and would cause a double
    mutex release [as the additional message completion would release it
    while its actually already free].

Change the flow to have a dedicated function to be called at end of each
flow and release the lock.

Modern VFs can't run on old non-compatible as the fastpath HSI is
slightly changed - but as the HSI is actually very close [basically,
a single bit whose meaning flipped] this can be supported with small
modifications.

The major differences would be in:
  - Recognizing that VF is running on top of a legacy PF.
  - Returning some slowpath configurations that are no longer needed
    on top of modern PFs, but would be required when working over
    the legacy ones.

Jeff Kirsher says:

====================
40GbE Intel Wired LAN Driver Updates 2016-08-19

This series contains updates to i40e and i40evf only.

Jake provides several patches, first just moves a function to co-locate
the two functions related to configuring RSS via the admin queue, which
should help in spotting bugs when comparing the two functions.  Fixed
an issue where commit e69ff813af ("i40e: rework the functions to
configure RSS with similar parameters") missed checking whether the seed
is NULL before using it and did not use the passed in *lut parameter.
Fixed an issue where a previous refactor missed i40e_vsi_config_rss()
and the values were being ignored, so checked for the fields and used
them instead of default values.  Lastly replaced calls to
create_singlethread_workqueue() with alloc_workqueue() to provide more
control over workqueue creation and allows explicit setting of the
desired mode of operation.

Mitch adds link speed to log messages and reports speed through ethtool.

Carolyn refactors tail bump check and fixes byte ordering problems found
when enabling this feature support.  Adds support for HMC resources and
profile commands for x722 firmware.

Heinrich Schuchardt fixes format identifiers from %u to %d since the
variable is defined as an integer.

Catherine fixes an issue where there was a race condition between the
completion of the client open and calls to the client ops, so ensured
that client ops are not called until we are sure client is open.

Harshitha makes sure that i40e_client_release() does not try to use
an adapter pointer which may not be initialized, so make sure it is.

Joe Perches fixes the use of the local macro XSTRINGIFY() to use
__stringify() instead.

Avinash corrects the mutex usage in client_subtask().  Fixed the RDMA
client to open again after reset since it is closed during a PF reset.

Jeff (me) clean up whitespace issues, where indentation was done
inconsistently and with spaces versus tabs.

The function i40e_client_release has a print statement that uses an
adapter pointer which is not initialized if a previous if statement
is not true. Hence, intialize it in the right place.

workqueue creation, and allows explicit setting of the desired mode of
operation. It also makes it more obvious that driver name constant is

552b996256 i40e: use configured RSS key and lookup table in i40e_vsi_config_rss
A previous refactor added support to store user configuration for VSIs,
so that extra VSIs such as for VMDq can use this information when
configuring. Unfortunately the i40e_vsi_config_rss function was missed
in this refactor, and the values were being ignored. Fix this by
checking for the fields and using those instead of always using the
default values.

776b2e15f8 i40e: fix broken i40e_config_rss_aq function
X722 hardware requires using the admin queue to configure RSS. This
function was previously re-written in commit e69ff813af ("i40e: rework
the functions to configure RSS with similar parameters").
However, the previous refactor did not work correctly for a few reasons

(a) it does not check whether seed is NULL before using it, resulting in
a NULL pointer dereference

(b) it does not even bother to use the passed in *lut parameter which
defines the requested lookup table. Instead it uses its own round robin
table.

Fix these issues by re-writing it to be similar to i40e_config_rss_reg
and i40e_get_rss_aq.

05fafbfb3d qed: utilize FW 8.10.10.0
This new firmware for the qed* adpaters fixes several issues:
 - Better blocking of malicious VFs.
 - After FLR, Tx-switching [internal routing] of packets might
   be incorrect.
 - Deletion of unicast MAC filters would sometime have side-effect
   of corrupting the MAC filters configred for a device.
It also contains fixes for future qed* drivers that *hopefully* would be
sent for review in the near future.

In addition, it would allow driver some new functionality, including:
 - Allowing PF/VF driver compaitibility with old drivers [running
   pre-8.10.5.0 firmware].
 - Better debug facilities.

This would also bump the qed* driver versions to 8.10.9.20.

Jeff Kirsher says:

====================
10GbE Intel Wired LAN Driver Updates 2016-08-18

This series contains updates to ixgbe and ixgbevf.

Emil cleans up confusing amongst the users by making an error message
into a debug message, since the TXDCTL.ENABLE (and comparable
VFTXDCTL.ENABLE for ixgbevf) bit is set only when the
transmit queue is actually enabled, which may not happen during the
configure phase eve if we waited for it.  Converts to using netdev_dbg()
macro instead of our home brewed macro for ixgbevf.  Converted the
service task to use atomic bitwise operations when setting and checking
reset requests to reduce the possibility of race conditions.
