Hi Russell,

this series applies on your net-queue branch.

It adds a new DSA switch operation which is used to determine a DSA
switch port's supported PHY interface modes to fill in phylink's config
supported_interfaces member to make SFP modules work under DSA ports.

This operation is then implemented for mv88e6xxx.

I was thinking whether this method should be renamed to something like
serdes_supported_interfaces or what, so that it is clear that we are
not interested in RGMII and other non-SERDES modes...

BTW: You once complained that you don't like that this needs again to
add a new op to DSA switch and for mv88e6xxx driver to add a new op for
the each chip... So maybe phylink_validate code can be refactored to do
this?
My opinion is that it is cleaner if we just add another op, but I am
open to other opinions.

Marek
