====================
sfc: bare bones TC offload

This series begins the work of supporting TC flower offload on EF100 NICs.
This is the absolute minimum viable TC implementation to get traffic to
 VFs and allow them to be tested; it supports no match fields besides
 ingress port, no actions besides mirred and drop, and no stats.
More matches, actions, and counters will be added in subsequent patches.

Changed in v2:
 - Add missing 'static' on declarations (kernel test robot, sparse)
