Hi,

If tx completion and start_xmit happen on 2 different CPUs, how do you
ensure that xmit_completion will observe the values written here?

Specifically, don't you need to move netdev_tx_sent_queue() before the
above memory barrier?

>>> Yes, you are correct. I'll update the changeset. Thank you.
