This is a note to let you know that I've just added the patch titled octeontx2-af: Add KPU changes to parse NGIO as separate layer to the 5.15-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: octeontx2-af-add-kpu-changes-to-parse-ngio-as-separa.patch and it can be found in the queue-5.15 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit ba5e9541fb588ac033a951338d64451681708dee Author: Kiran Kumar K <kirankumark@xxxxxxxxxxx> Date: Fri Jan 21 12:04:47 2022 +0530 octeontx2-af: Add KPU changes to parse NGIO as separate layer [ 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.
