Subject: [PATCH 09/14] flow_dissector: detect DSA using skb->protocol even when VLAN tag is present
Date: Mon,  7 Nov 2022 19:54:47 +0100	[thread overview]
Message-ID: <20221107185452.90711-9-nbd@nbd.name> (raw)
In-Reply-To: <20221107185452.90711-1-nbd@nbd.name>

Fixes flow dissection with ethernet devices that can combine VLAN rx hwaccel
with DSA, since skb->protocol is set to htons(ETH_P_XDSA) by the network stack.
