net l2tp: drop flow hash on forward
[ Upstream commit 42f853b4 ] 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. One such example is the Mediatek Filogic MT798x family of networking processors.
