net: phylink: make QSGMII a valid PHY mode for in-band AN
QSGMII is a SerDes protocol clocked at 5 Gbaud (4 times higher than SGMII which is clocked at 1.25 Gbaud), with the same 8b/10b encoding and some extra symbols for synchronization. Logically it offers 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, since it is no different from software perspective from regular SGMII. Signed-off-by:Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by:
