Subject[PATCH net-next 0/6] net: phy: Remove probe_capabilities
Date
With all the drivers which used .probe_capabilities converted to the
new c45 MDIO access methods, we can now decide based upon these whether
a bus driver supports c45 and we can get rid of the not widely used
probe_capabilites.

Unfortunately, due to a now broader support of c45 scans, this will
trigger a bug on some boards with a (c22-only) Micrel PHY. These PHYs
don't ignore c45 accesses correctly, thinking they are addressed
themselves and distrupt the MDIO access. To avoid this, a blacklist
for c45 scans is introduced.
