====================
Intel Wired LAN Driver Updates

This series contains updates to i40e and i40evf.

Greg provides two patches for i40e, the first adds the netdev ops to support
the addition of static FDB entries in the physical function (PF) MAC/VLAN
filter table so that the virtual functions (VFs) can communicate with
bridged virtual Ethernet ports such as those provided by the virtio
driver.  The second is to fix an issue where the assignment of a port
VLAN after it is already up and running requires the VF driver to be
reloaded, so print a message warning the host administrator about the
need to reload the VF driver.  In addition, knock the VF offline so that
it does not continue to receive traffic not on the port VLAN assigned to
it.

Jesse provides a patch for i40e and i40evf to unhide and enable the
PREFENA field in the receive host memory cache (RX-HMC) for best
performance.

Mitch provides a i40e patch to implement the net device op for Tx
bandwidth setting.

Catherine removes a firmware workaround that is no longer needed with
the latest firmware for i40e.  She also provides some minor cleanups
as well bumps the driver versions.

Anjali provides a fix for i40e displaying IPv4 flow director filters
which needed additional information to be communicated up above in
order for it to be displayed correctly.

Shannon adds tracking of the NVM busy state so that the driver won't
allow a new NVM update command until a completion event is received
from the current update.  Updates the admin queue API to reflect
recent changes in the firmware.  Also rearranges the "if netdev" logic
to prepare for handling non-netdev VSIs.  Lastly rework the fdir
setup and tear down to use the newly created i40e_vsi_open() and
i40e_vsi_close(), which also fixes a memory leak of the FDIR queue
buffer info structs across a reset.
