Subject: [PATCH net-next 0/3] net: stmmac: phylink PCS conversion part 3

Hi,

This series is currently the last of the phylink PCS conversion for
stmmac. This series contains changes that will cause potential breakage,
so I suggest to netdev maintainers that it is only applied if there is
a significant response from testers using the PCS.

Paritcularly, dwmac-qcom-ethqos.c users need to test this, since this
platform glue driver manipulates the PCS state. Patch 2 is designed to
print a warning to the kernel log if this glue driver calls
stmmac_pcs_ctrl_ane() to set the AN state differently to how phylink
has set it. If this happens, we need to do some pre-work to prevent
these prints.
