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