From: Jianbo Liu <[email protected]>
For ICMPv4, the checksum is calculated from the ICMP headers and data.
Since the ICMPv4 checksum doesn't cover the IP header, we can allow to
do L3 header re-write for this protocol.
Fixes: bdd66ac0aeed ('net/mlx5e: Disallow TC offloading of unsupported
match/action combinations')
