From 22171213e503edce38f249cff82b9ad3775b9026 Mon Sep 17 00:00:00 2001 From: Russell King Date: Fri, 15 Jan 2021 23:36:39 +0000 Subject: [PATCH] arm64: dts: lx2160a-cex7: increase at8035 PHY gigabit Tw parameter Increase the SmartEEE Tw parameter for Atheros PHYs to stop gigabit links from sporadically dropping. Testing on this platform shows that a value of 24 results in a stable link, whereas 23 or below has the occasional drop. Tested with a Netgear GS116 unmanaged switch link partner with Cat 5e cabling.
