[PATCH 5.0 21/52] scsi: qla2xxx: Fix FC-AL connection target discovery

From: Greg Kroah-Hartman
Date: Tue Mar 26 2019 - 02:40:11 EST


5.0-stable review patch. If anyone has any objections, please let me know.

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

From: Quinn Tran <qtran@xxxxxxxxxxx>

commit 4705f10e82c63924bd84a9b31d15839ec9ba3d06 upstream.

Commit 7f147f9bfd44 ("scsi: qla2xxx: Fix N2N target discovery with Local
loop") fixed N2N target discovery for local loop. However, same code is
used for FC-AL discovery as well. Added check to make sure we are bypassing
area and domain check only in N2N topology for target discovery.
