Merge branch 'octeontx2-refactor'

Naveen Mamindlapalli says:

====================
refactor code related to npc install flow

This patchset refactors and cleans up the code associated with the
npc install flow API, specifically to eliminate different code paths
while installing MCAM rules by AF and PF. This makes the code easier
to understand and maintain. Also added support for multi channel NIX
promisc entry.
