Subject: [RFC PATCH net-next 0/8] Convert xpcs to phylink_pcs_ops

From: Vladimir Oltean <vladimir.oltean@....com>

This patch series is COMPLETELY UNTESTED (I don't have stmmac hardware
with the xpcs) hence the RFC tag. If people from Intel could test this
it would be great.

Background: the sja1105 DSA driver currently drives a Designware XPCS
for SGMII and 2500base-X, and it would be nice to reuse some code with
the xpcs module. This would also help consolidate the phylink_pcs_ops,
since the only user of that, currently, is the lynx_pcs.

Therefore, this series makes the xpcs expose the same kind of API that
the lynx_pcs module does.

Note: this patch series must be applied on top of:
