Merge branch 'nfp-flower-fixes'

Jakub Kicinski says:

====================
nfp: flower: fixes for flower offload

Two fixes for flower matching and tunnel encap.  Pieter fixes
VLAN matching if the entire VLAN id is masked out and match
is only performed on the PCP field.  Louis adds validation of
tunnel flags for encap, most importantly we should not offload
actions on IPv6 tunnels if it's not supported.
