+Subject: [PATCH] net: phylink: make QSGMII a valid PHY mode for in-band AN
+
+QSGMII is just SGMII clocked at a higher frequency (5 Gbaud vs 1.25
+Gbaud). Logically it is just 4 SGMII interfaces multiplexed onto the
+same physical lanes. Each MAC PCS has its own in-band AN process with
+the system side of the QSGMII PHY, which is identical to the regular
+SGMII AN process. So allow QSGMII as a valid in-band AN mode.
