Russell King (Oracle) 5f44dfa841 net: pcs: xpcs: remove double-read of link state when using AN ...

[ Upstream commit ef63461caf ]

Phylink does not want the current state of the link when reading the
PCS link state - it wants the latched state. Don't double-read the
MII status register. Phylink will re-read as necessary to capture
transient link-down events as of dbae3388ea ("net: phylink: Force
retrigger in case of latched link-fail indicator").

The above referenced commit is a dependency for this change, and thus
this change should not be backported to any kernel that does not
