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

This series contains updates to i40e only.

Anjali adds more functionality to debugfs to assist development and
testing of admin queue commands.

Greg makes sure broadcast promiscuous is disabled by default, otherwise
VLAN tagged packets out of the assigned VLAN domain are received.  Also
provides a fix when the 8021q driver is loaded, so that VLAN 0 tagged
packets are accepted so that upper layers can interpret the priority
bits. Then provides a fix to let the VF to request the PF to set its
already assigned MAC address without generating an error.  Greg also
adds helper functions to enable or disable internal switch loopback
when VFs are created or destroyed via the sysfs interface.

Shannon provides most of the changes, where he adds code to ensure
that the hardware waits to make sure that the firmware is ready as well
after reset.  Also updates the code to use the new features in the
firmware.  Provides a fix while in MFP mode where resources are
reduced, so use a smaller range of test registers than when in SFP mode.
Moves the PF ID initialization code to earlier in the driver
initialization function since a few operations need the information
before the first PF reset is called.  Shannon adds a check for MAC
type before reading anything from the registers to ensure we dealing
with the correct MAC type.  Then reworks Shadow RAM read word/buffer
functions as to not block whole NVM resources for SR read operations.

Mitch lastly provides a fix to correctly setup ARQ descriptors in
the cleanup code.

Catherine bumps the driver version due to all the recent changes.

v2:
 - Added blank lines after local variable declarations to patch 01
   as suggested by David Miller
 - Used the suggested memset() line in patch 15 as suggested by David
   Miller
