Subject[PATCH 4.4 09/16] lpfc: Fix Device discovery failures during switch reboot test.
Date
4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: James Smart <james.smart@broadcom.com>

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.
