From 0d40b6101fe41a14ebd871adefa2a7b844b1d309 Mon Sep 17 00:00:00 2001 From: "Lendacky, Thomas" Date: Fri, 16 Jan 2015 12:47:10 -0600 Subject: [PATCH] amd-xgbe-phy: Use the proper auto-negotiation XNP registers When receiving and processing extended next pages the base registers were used instead of the XNP registers. Update the code to use the device XNP and link partner XNP registers. Signed-off-by: Tom Lendacky Signed-off-by: David S.
