[v3,07/10] net/sfc: override match on ETH in tunnel offload JUMP rules
Checks
Commit Message
The current HW/FW doesn't allow to match on MAC addresses in outer rules.
One day this will change for sure, but right now a workaround is needed.
Match on VLAN presence in outer rules is also unsupported. Ignore it.
