From 77316763321ee4050f0576ffd472183aa90dcb30 Mon Sep 17 00:00:00 2001 From: Russell King Date: Sun, 2 Jun 2019 15:12:54 +0100 Subject: [PATCH] net: phylink: avoid reducing support mask Avoid reducing the support mask as a result of the interface type selected for SFP modules, or when setting the link settings through ethtool - this should only change when the supported link modes of the hardware combination change.
