From d526228a8159d136c914c8f71d5944cda2f93d9a Mon Sep 17 00:00:00 2001 From: Vladimir Oltean Date: Thu, 28 Nov 2019 03:21:53 +0200 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.
