One issue is reported by David Marchand that error occurs in OVS due to
the fix patch in mentioned changes below. The detailed reproduce step
and result are in https://patchwork.dpdk.org/project/dpdk/patch/
20211207085946.121032-1-dapengx...@intel.com/.
This patch removes unnecessary link status check and directly sets mac
config in dev_start. Also, it sets the parameter "wait to complete" true
to wait for more time to make sure adminq command execute completed.
Fixes: a4ba77367923 ("net/i40e: enable maximum frame size at port level")
Fixes: 2184f7cdeeaa ("net/i40e: fix max frame size config at port level")
Fixes: 719469f13b11 ("net/i40e: fix jumbo frame Rx with X722")
