4.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Quinn Tran <redacted>
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.
Fixes: 726b85487067 ("qla2xxx: Add framework for async fabric discovery")
