Subject: [PATCH net-next 5/7] octeontx2-af: Add IPv6 fields to default MKEX

From: Vidhya Vidhyaraman <vraman@...vell.com>

Added some IPv6 protocol fields to the default MKEX profile.
They include everything from the beginning of IP header and up to
source address. The pattern occupies full KW2 in MCAM entry.
Only one out of two LD registers for this protocol is used.
