Subject: [PATCH net-next 0/4] net: phy: xpcs: Link errors improvements

First set of improvements for XPCS that were developed after exhaustive
tests of Link Down / Link Up transitions.

As a side note, more fixes and improvements may come in the near future
as we are adding XLGMII support at 25G, 40G, 50G and 100G speeds for
both XPCS and stmmac drivers.

Patch 1/4, prevents reading old values from RX/TX fault.

Patch 2/4 and 3/4, signals the check link function for critical errors
that can disturbe link normal operation and that need XPCS reset.

Patch 4/4, resets the XPCS at probe so that we start from a well known
state.
