Subject: net: phylink: Allow 2.5BASE-T, 5GBASE-T and 10GBASE-T for the 10G
 link modes
Patch-mainline: v5.6-rc1
Git-commit: 6cbdcf25bdec944f85bb2ef7ebe959bdb7dc59b8
References: bsc#1176447

For some reason, PHYLINK does not put the copper modes for 802.3bz
(NBASE-T) and 802.3an-2006 (10GBASE-T) in the PHY's supported mask, when
the PHY-MAC connection is a 10G-capable one (10GBase-KR, 10GBase-R,
USXGMII). One possible way through which the cable side can work at the
lower speed is by having the PHY emit PAUSE frames towards the MAC. So
fix that omission.

Also include the 2500Base-X fiber mode in this list while we're at it.
