[PATCH 4.4.x] lpfc: Fix Device discovery failures during switch reboot test.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: James Smart <james.smart@xxxxxxxxxxxx>

commit 342b59caa66240b670285d519fdfe2c44289b516 upstream.

When the switch is rebooted, the lpfc driver fails to log
into the fabric, and Unexpected timeout message is seen.

Fix: Do not issue RegVFI if the FLOGI was internally aborted.

Needed on IBM Petitboot environment - without it, we get
extreme delays in kexec to distro.
