[PATCH net,5/6] octeontx2-af: fix issue with IPv4 match for RSS
From: Srujana Challa
Date: Mon Jul 01 2024 - 05:09:05 EST
From: Satheesh Paul <psatheesh@xxxxxxxxxxx>
While performing RSS based on IPv4, packets with
IPv4 options are not being considered. Adding changes
to match both plain IPv4 and IPv4 with option header.
Fixes: 41a7aa7b800d ("octeontx2-af: NIX Rx flowkey configuration for RSS")
