Subject: sfc: Fix reading non-legacy supported link modes
From: Erik Ekman <erik@xxxxxxx>
commit 041c61488236a5a84789083e3d9f0a51139b6edf upstream.
Everything except the first 32 bits was lost when the pause flags were
added. This makes the 50000baseCR2 mode flag (bit 34) not appear.
I have tested this with a 10G card (SFN5122F-R7) by modifying it to
return a non-legacy link mode (10000baseCR).
