Cover letter [PATCH v2 net-next 0/4] sfc: more flexible encap matches on TC decap rules

From: Edward Cree <[email protected]>

This series extends the TC offload support on EF100 to support optionally
matching on the IP ToS and UDP source port of the outer header in rules performing tunnel decapsulation. Both of these fields allow masked matches if the underlying hardware supports it (current EF100 hardware supports masking on ToS, but only exact-match on source port).
Given that the source port is typically populated from a hash of inner
header entropy, it's not clear whether filtering on it is useful, but since we can support it we may as well expose the capability.

Edward Cree (4):
sfc: release encap match in efx_tc_flow_free()
sfc: populate enc_ip_tos matches in MAE outer rules
sfc: support TC decap rules matching on enc_ip_tos
sfc: support TC decap rules matching on enc_src_port
