[RFC PATCH v2 0/9] provide cable test support for the ksz886x

From: Oleksij Rempel
Date: Mon May 10 2021 - 08:50:01 EST

changes v2:
- use generic MII_* defines where possible
- rework phylink validate
- remove phylink get state function
- reorder cabletest patches to make PHY flag patch in the right order
- fix MDI-X detection

This patches provide support for cable testing on the ksz886x switches.
Since it has one special port, we needed to add phylink with validation
and extra quirk for the PHY to signal, that one port will not provide
valid cable testing reports.
