Subject: [PATCH net] octeontx2-af: Fix npc_delete_flow counter read for cn20k
Date: Fri, 23 Oct 2026 10:01:12 +0000 [thread overview]
Message-ID: <20261023100112.3402726-1-vmukunda@marvell.com> (raw)
From: Subbaraya Sundeep <sbhatta@marvell.com>
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")
