Subject: [PATCH net-next] net: remove explicit phylink_generic_validate()
references
Virtually all conventional network drivers are now converted to use
phylink_generic_validate() - only DSA drivers and fman_memac remain,
so lets remove the necessity for network drivers to explicitly set
this member, and default to phylink_generic_validate() when unset.
This is possible as .validate must currently be set.
Any remaining instances that have not been addressed by this patch can
be fixed up later.
