[PATCH 4.19 097/205] scsi: qla2xxx: Initialize port speed to avoid setting lower speed

From: Greg Kroah-Hartman
Date: Mon Nov 19 2018 - 11:34:28 EST


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

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

From: Quinn Tran <quinn.tran@xxxxxxxxxx>

commit f635e48e866ee1a47d2d42ce012fdcc07bf55853 upstream.

This patch initializes port speed so that firmware does not set lower
operating speed. Setting lower speed in firmware impacts WRITE perfomance.
