Subject: [PATCH 611/660] 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.
