I deliberately disable EDPD for PHY_MAC_INTERRUPT as well.
That's a proper interrupt, i.e. the PHY signals interrupts
to the MAC (e.g. through an interrupt pin on the MAC),
which forwards the interrupts to phylib. EDPD cannot
be used in that situation either.

Personally I think checking for PHY_POLL is succinct,
but if you or anyone else feels strongly about it
I'll be happy to add such a static inline to
include/linux/phy.h.
