Subject: [PATCH net,4/6] octeontx2-af: Fix issue with IPv6 ext match for RSS

From: Kiran Kumar K <kirankumark@...vell.com>

While performing RSS based on IPv6, extension ltype
is not being considered. This will be problem for
fragmented packets or packets with extension header.
Adding changes to match IPv6 ext header along with IPv6
ltype.
