From b44592ffb8e0da32f1d17f1586a9d2c59dd152a1 Mon Sep 17 00:00:00 2001 From: Russell King Date: Tue, 8 Jul 2014 00:22:34 +0100 Subject: [PATCH] net: fec: iMX6 FEC does not support half-duplex gigabit The iMX6 gigabit FEC does not support half-duplex gigabit operation. Phys attacked to the FEC may support this, and we currently do nothing to disable this feature. This may result in an invalid configuration. Mask out phy support for gigabit half-duplex operation.
