From 4381ffdfb32ba2674eb8170114ae2bbfdcb24db0 Mon Sep 17 00:00:00 2001 From: "Lendacky, Thomas" Date: Tue, 28 Feb 2017 15:02:51 -0600 Subject: [PATCH] amd-xgbe: Stop the PHY before releasing interrupts [ Upstream commit 402168b4c2dc0734b8fbd282eff77da0275c5129 ] Some configurations require the use of the hardware's MDIO support to communicate with external PHYs. The MDIO commands indicate completion through the device interrupt. When bringing down the device the interrupts were released before stopping the external PHY, resulting in MDIO command timeouts. Move the stopping of the PHY to before the releasing of the interrupts. Signed-off-by: Tom Lendacky Signed-off-by: David S.
