[PATCH 5.15 109/262] octeontx2-af: Add KPU changes to parse NGIO as separate layer

From: Greg Kroah-Hartman
Date: Mon Mar 07 2022 - 05:03:02 EST


From: Kiran Kumar K <kirankumark@xxxxxxxxxxx>

[ Upstream commit 745166fcf01cecc4f5ff3defc6586868349a43f9 ]

With current KPU profile NGIO is being parsed along with CTAG as
a single layer. Because of this MCAM/ntuple rules installed with
ethertype as 0x8842 are not being hit. Adding KPU profile changes
to parse NGIO in separate ltype and CTAG in separate ltype.

Fixes: f9c49be90c05 ("octeontx2-af: Update the default KPU profile and fixes")
