From 41033b65b98388cb255c0307ea869856f71ca80d Mon Sep 17 00:00:00 2001 From: Michael Chan Date: Tue, 31 Dec 2013 23:22:33 -0800 Subject: [PATCH] bnx2: Enable auto-mdix when autoneg is disabled. Auto-mdix currently only works if autoneg is enabled. This patch enables auto-mdix all the time by setting a bit in a PHY register. Define meaningful constants for this PHY registers.
