[PATCH net-next 0/3] net: enetc: phylink validate implementation updates

[Russell King (Oracle)]

This series converts enetc to fill in the supported_interfaces member
of phylink_config, cleans up the validate() implementation, and then
converts to phylink_generic_validate().

[PATCH net-next 1/3] net: enetc: populate supported_interfaces member

[Russell King (Oracle)]

[PATCH net-next 2/3] net: enetc: remove interface checks in enetc_pl_mac_validate()

[Russell King (Oracle)]

As phylink checks the interface mode against the supported_interfaces
bitmap, we no longer need to validate the interface mode in the
validation function. Remove this to simplify it.

[PATCH net-next 3/3] net: enetc: use phylink_generic_validate()

[Russell King (Oracle)]

enetc has no special behaviour in its validation implementation, so can
be switched to phylink_generic_validate().
