From dcbf8f8087ebc4d721fd55c4c2072f1a97f6ef6d Mon Sep 17 00:00:00 2001 From: Sawan Chandak Date: Thu, 24 Jan 2019 23:23:48 -0800 Subject: [PATCH] scsi: qla2xxx: Restore FAWWPN of Physical Port only for loop down When loop was made down explicitly due to cable pull, then for N2N toplogy, if FAWWPN BIT is enabled by user, then it would restore some default (garbage) value for Physical port WWPN, so this show garbage WWPN for the port. Fix is, to restore physical port WWPN, if it is fabric configuration. When loop is explicitly made down, and FAWWPN feature is enabled, then driver need to restore original flashed WWPN.
