====================
40GbE Intel Wired LAN Driver Updates 2019-08-05

This series contains updates to i40e driver only.

Dmitrii adds missing statistic counters for VEB and VEB TC's.

Slawomir adds support for logging the "Disable Firmware LLDP" flag
option and its current status.

Jake fixes an issue where VF's being notified of their link status
before their queues are enabled which was causing issues.  So always
report link status down when the VF queues are not enabled.  Also adds
future proofing when statistics are added or removed by adding checks to
ensure the data pointer for the strings lines up with the expected
statistics count.

Czeslaw fixes the advertised mode reported in ethtool for FEC, where the
"None BaseR RS" was always being displayed no matter what the mode it
was in.  Also added logging information when the PF is entering or
leaving "allmulti" (or promiscuous) mode.  Fixed up the logging logic
for VF's when leaving multicast mode to not include unicast as well.

v2: drop Aleksandr's patch (previously patch #2 in the series) to
    display the VF MAC address that is set by the VF while community
    feedback is addressed.
