Saeed,

We should be aiming to patch the driver around this issue with
something that goes all the way back through -stable to the very 1st
upstream kernel supporting mlx5 EN --- the operational link doesn't go
down when instructed by the admin and this is an entry level
requirement from Ethernet of things (such as NIC and Switch ports).
