From 99122836d26a366847f92f9a211602a44a038c61 Mon Sep 17 00:00:00 2001 From: Voon Weifeng Date: Tue, 27 Aug 2019 09:38:08 +0800 Subject: [PATCH] net: stmmac: add EHL SGMII 1Gbps PCI info and PCI ID Added EHL SGMII 1Gbps PCI ID. Different MII and speed will have different PCI ID. Signed-off-by: Voon Weifeng Signed-off-by: Ong Boon Leong Signed-off-by: David S.
