At start of commands, QLogic port is ACTIVE whereas the Mellanox port is
DOWN.

IBA spec says:
C14-24.2.1: If PortInfo:Portstate=Down, then
• a SubnGet(PortInfo) shall produce valid data for PortInfo:PortState
and PortInfo:PortPhysicalState; whether any other component has
valid data is vendor-dependent.
• a SubnSet(PortInfo) shall make any changes it specifies to PortInfo:
PortPhysicalState; any other result is vendor-dependent.

so when port is down only things in PortInfo you can trust are PortState
and PortPhysicalState and you can't expect anything else to work.

Bring port up at least to INIT and retry.
