Hi,

This series adds support for IEEE 802.3 register set compliant PCS
for phylink.  In order to do this, we:

1. convert the existing (unused) mii_lpa_to_ethtool_lpa_x() function
   to a linkmode variant.
2. add a helper for clause 37 advertisements, supporting both the
   1000baseX and defacto 2500baseX variants. Note that ethtool does
   not support half duplex for either of these, and we make no effort
   to do so.
3. add accessors for modifying a MDIO device register, and use them in
   phylib, rather than duplicating the code from phylib.
4. add support for decoding the advertisement from clause 22 compatible
   register sets for clause 37 advertisements and SGMII advertisements.
5. add support for clause 45 register sets for 10GBASE-R PCS.

These have been tested on the LX2160A Clearfog-CX platform.
