Subject: [PATCH net-next 4/6] flow_dissector: Include VLAN ID in hash computation
Date: Fri, 27 Feb 2015 19:11:47 -0800 [thread overview]
Message-ID: <1425093109-1077-5-git-send-email-therbert@google.com> (raw)
In-Reply-To: <1425093109-1077-1-git-send-email-therbert@google.com>
If VLAN is present include that in hash_extra in flow_keys when
dissecting. This will then be included in hash computation.
