Subject: [PATCH] net/nfp: fix TP flow action for UDP
Date: Fri, 9 Jun 2023 14:22:19 +0800 [thread overview]
Message-ID: <20230609062219.1308140-1-chaoyong.he@corigine.com> (raw)
The former logic can't distinguish the TCP and UDP set action, and
only send a TCP type ctrl message to firmware, which cause the set
action of UDP can't offload.
Fixes: fc185097bbe6 ("net/nfp: support TP source flow action")
Fixes: 87986df09d75 ("net/nfp: support TP destination flow action")
