From 3a7ed5aa232da1d2836b5d3962e59e685307122e Mon Sep 17 00:00:00 2001 From: Shaohui Xie Date: Tue, 22 Apr 2014 18:21:37 +0800 Subject: [PATCH] powerpc/fman/memac: use default MDIO_HOLD value Current driver uses a Maximum value for MDIO_HOLD when doing 10G MDIO access, this is due to an errata A-006260 on T4 rev1.0 which is fixed on rev2.0, so remove the maximum value to use the default value for rev2.0.
