This patch handles a corner case where TX packet would remain in
driver queue till next packet comes in.
Here is sequence:
1. TX packet is queued via hard_start_xmit and main_work is queued
2. SDIO interrupt comes in which directly call mwifiex_main_process.
This starts executing main superloop.
3. Now work from step1 is scheduled but at first check itself it sees
mwifiex_processing is set and exits.
4. Now if superloop from step2 has passed TX processing part of superloop
this packet would remain in queue until next packet/command/SDIO interrupt
arrives and queues main_work.

This patch fixes this corner case by defining more_task flag which is set when
mwifiex_processing is found to be true. At end of superloop we again check if
more_task flag is set and if set, execute superloop again.

Intel Wired LAN Driver Updates 2015-02-24

This series contains updates to i40e and i40evf only, which bumps their
versions to i40e 1.2.9 and i40evf 1.2.3.

Paul fixes i40e_debug_aq() for big endian machines by adding the
appropriate LExx_TO_CPU wrappers.

Catherine adds a requested speed variable to the link_status to store the
last speeds we requested from the firmware and use the advertised speed
settings in get_settings in ethtool now that we have it.  Due to the
new code addition, she also refactors get_settings to improve readability
and to accommodate some of the longer lines of code by adding two
functions i40e_get_settings_link_up() and i40e_get_settings_link_down().

Carolyn adds a struct to the VSI struct to keep track of RXNFC settings
done via ethtool.  Adds more information to the interrupt vector
names, specifically to the VF misc vector name so that we can distinguish
between all the interrupts.

Ashish enables the i40evf driver to enable debug prints via ethtool.

Mitch updates i40e to enable packet split only when IOMMU is in use,
since it shows a distinct advantage over the single-buffer path
because it minimizes DMA mapping and unmapping.  Also adds the receive
routine in use to the features log message to be able to print the
receive packet split status.

Greg adds the ability to get, set and commit permanently the NPAR
partition BW configuration through configfs.  Enables an application
to query the i40e driver's private flags to get the status of NPAR
enablement via ethtool.

Neerav adds support for bridge offload ndo_ops getlink and setlink
to enable bridge hardware mode as per the mode set via IFLA_BRIDGE_MODE.
The support is only enabled in the case of a PF VSI and not available for
any other VSI type.

Kevin fixes i40e by ensuring the BUF and FLAG_RD flags are set for
indirect admin queue command.

Vasu updates the driver to setup FCoE netdev device type as "fcoe", so that
it shows up in sysfs as FCoE device.

net: dsa: integration with SWITCHDEV for HW bridging

This patch set provides the DSA and SWITCHDEV integration bits together and
modifies the bcm_sf2 driver accordingly such that it works properly with HW
bridging.

Changes in v3:

- add back the null pointer check in dsa_slave_br_port_mask from Guenter
- slightly rework patch 1 commit message not to mention the function name
  we add in patch 2

Changes in v2:

- avoid a race condition in how DSA network devices are created, patch from
  Guenter Roeck
- provide a consistent and work STP state once a port leaves the bridge
- retain a bridge device pointer to properly flag port/bridge membership
- properly flush the ARL (Address Resolution Logic) in bcm_sf2.c
- properly retain port membership when individually bringing devices up/down
  while they are members of a bridge

We discussed on the mailing-list the possibility of standardizing a "fdb_flush"
operation for DSA switch drivers, looking at the Marvell and Broadcom switches,
I am not convinced this is practical or diserable as the terminologies vary
here, but there is nothing preventing us from doing it later.

Many thanks to Guenter and Andrew for both testing and providing feedback.
