octeontx2-af: Use hashed field in MCAM key
CN10KB variant of CN10K series of silicons supports
a new feature where in a large protocol field
(eg 128bit IPv6 DIP) can be condensed into a small
hashed 32bit data. This saves a lot of space in MCAM key
and allows user to add more protocol fields into the filter.
A max of two such protocol data can be hashed.
This patch adds support for hashing IPv6 SIP and/or DIP.
