Subject: [PATCH] net/i40e: fix X722 NIC receives jumbo frame packets
For NIC I40E_10G-10G_BASE_T_X722, when the port is configured with
link speed, it cannot receive jumbo frame packets.
Because it set maximum frame size failed when starts the port that the
port link status is still down.
This patch fix the error that starts the port will force set maximum frame
size.

It seems this fix has been missed in 21.11 (for the reason we
discussed with Kevin offlist).
Our QE reported that reception of jumbo frames seems broken in the 21.11 branch.
I can reproduce with a X710 nic: v21.11.0 is fine, but v21.11.1 and
v21.11.2 show the following error log.
Dec 05 05:41:37 xxx ovs-vswitchd[53585]:
ovs|00183|dpdk|ERR|i40e_set_mac_max_frame(): Set max frame size at
port level not applicable on link down
The log goes away with backporting this current patch.
Can this be added to 21.11 queue, and have Intel validate this issue?
Thanks David. I am have applied and pushing through CI. Will push to
21.11 branch when it completes.
Thanks!
