Subject: scsi: lpfc: Vport creation is failing with "Link Down" error
Patch-mainline: v4.13-rc1
Git-commit: 56bc802842839174befc97749ea01d4004275c14
References: bsc#1050239,FATE#322918
Vport creation fails for SLI-3 adapters.
Mailbox submission fails because mailbox interrupt is disabled. Mailbox
interrupt is disabled during port reset.
Do reset only for physical port.
