Subject: [PATCH] net: phylink: call mac_an_restart for SGMII/QSGMII inband
interfaces too
It doesn't quite make sense why restarting the AN process should be
unique to 802.3z (1000Base-X) modes. It is valid to put an SGMII PCS in
in-band AN mode, therefore also make PHYLINK re-trigger an
auto-negotiation if needed.
