-Subject: [PATCH] net l2tp: drop flow hash on forward
-
-Drop the flow-hash of the skb when forwarding to the L2TP netdev.
-
-This avoids the L2TP qdisc from using the flow-hash from the outer
-packet, which is identical for every flow within the tunnel.
-
-This does not affect every platform but is specific for the ethernet
-driver. It depends on the platform including L4 information in the
-flow-hash.
