[PATCH net] octeontx2-af: Fix npc_delete_flow counter read for cn20k
From: vmukunda
Date: Fri Oct 23 2026 - 06:01:53 EST
From: Subbaraya Sundeep <sbhatta@xxxxxxxxxxx>
On cn20k, the MCAM match counter cannot be read from
NPC_AF_MATCH_STATX. Skip reading the counter value in
npc_delete_flow on cn20k. Counter support for cn20k is TBD.
Fixes: 5f83b4729440 ("octeontx2-af: Do not access match stats for cn20k")
