====================
Minor fixes for pcs_get_state() implementations

This series contains a number fixes for minor issues with some
pcs_get_state() implementations, particualrly for the phylink
state->an_enabled member. As they are minor, I'm suggesting we
queue them in net-next as there is follow-on work for these, and
there is no urgency for them to be in -rc.

Just like phylib, state->advertising's Autoneg bit is a copy of
state->an_enabled, and thus it is my intention to remove
state->an_enabled from phylink to simplify things.

This series gets rid of state->an_enabled assignments or
reporting that should never have been there.
