From: Kristof Provost <k...@freebsd.org>
If control packets come in through the DCO interface (i.e. via
dco_do_read()) we must process them through process_incoming_link().
This doesn't currently manifest, because Linux passes control packets
through the regular socket, not via the DCO netlink interface, but other
platforms will not.
