6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: ChunHao Lin <hau@xxxxxxxxxxx>
commit 868c3b95afef4883bfb66c9397482da6840b5baf upstream.
Device that support DASH may be reseted or powered off during suspend.
So driver needs to handle DASH during system suspend and resume. Or
DASH firmware will influence device behavior and causes network lost.
Fixes: b646d90053f8 ("r8169: magic.")
