commit 416186fbf8c5b4e4465 ("net: Split core bits of netdev_pick_tx
|
|
into __netdev_pick_tx") added a bug that disables caching of queue
|
|
index in the socket.
|
|
|
|
This is the source of packet reorders for TCP flows, and
|
|
again this is happening more often when using FQ pacing.
|
|
|
|
Old code was doing
|
|
|
|
if (queue_index != old_index)
|
|
sk_tx_queue_set(sk, queue_index);
|
|
|
|
Alexander renamed the variables but forgot to change sk_tx_queue_set()
|
|
2nd parameter.
|
|
|
|
if (queue_index != new_index)
|
|
sk_tx_queue_set(sk, queue_index);
|
|
|
|
This means we store -1 over and over in sk->sk_tx_queue_mapping
