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.
