Subject: [PATCH net-next v3 00/11] net: mdio: Start separating C22 and C45

I've picked this older series from Andrew up and rebased it onto
v6.2-rc1.

This patch set starts the separation of C22 and C45 MDIO bus
transactions at the API level to the MDIO Bus drivers. C45 read and
write ops are added to the MDIO bus driver structure, and the MDIO
core will try to use these ops if requested to perform a C45
transfer. If not available a fallback to the older API is made, to
allow backwards compatibility until all drivers are converted.

A few drivers are then converted to this new API.

The core DSA patch was dropped for now as there is still an ongoing
discussion. It will be picked up in a later series again.
