From 4446e9789e662fe53dfcfe34551b5b74a013086c Mon Sep 17 00:00:00 2001 From: Vladimir Oltean Date: Fri, 22 Nov 2019 13:46:46 +0200 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.
