40GbE Intel Wired LAN Driver Updates 2018-01-10

This series contains updates to i40e and i40evf only.

Alice adds the displaying of priority xon/xoff packet stats, since we
were already keeping track of them.  Based on the recent changes, bump
the driver versions.

Jake changes how the driver determines whether or not the device is
currently up to resolve the possible issue of freeing data structures
and other memory before they have been fully allocated.  Refactored
the driver to simplify the locking behavior and to consistently use
spinlocks instead of an overloaded bit lock to protect MAC and filter
lists.  Created a helper function which can convert the AdminQ link
speed definition into a virtchnl definition.

Colin Ian King cleans up a redundant variable initialization.

Alex cleans up the driver to stop clearing the pending bit array for
each vector manually, since it is prone to dropping an interrupt and
based on the hardware specs, the pending bit array will be cleared
automatically in MSI-X mode.  Cleaned up flags for promiscuous mode to
resolve an issue where enabling & disabling promiscuous mode on a VF
would leave us in a high polling rate for the adminq task.  Cleaned up
code that was prone to race issues.

Jingjing renames pipeline personalization profile (ppp) to dynamic
device personalization (ddp) because it was being confused with the
well known point to point protocol.  Also removed checks for "track_id"
being zero, since it is valid for it to be zero for profiles that do
not have any 'write' commands.

v2: cleaned up commit message for patch 12 based on feedback from Sergei
    Shtylyov and Alex Duyck
v3: dropped patch 15 from the original series while Mariusz Stachura
    works on the changes that Jakub Kicinski has suggested
