Subject: net: phylink: allow in-band AN for USXGMII
Patch-mainline: v5.6-rc1
Git-commit: 04e2246329d4a72c2ec8ebd1ebc3f7250dece2da
References: bsc#1176447

USXGMII supports passing link information in-band between PHY and MAC PCS,
add it to the list of protocols that support in-band AN mode.

Being a MAC-PHY protocol that can auto-negotiate link speeds up to 10
Gbps, we populate the initial supported mask with the entire spectrum of
link modes up to 10G that PHYLINK supports, and we let the driver reduce
that mask in its .phylink_validate method.
