From 61369d0259a724606f3941a46d2c75155d66cf2c Mon Sep 17 00:00:00 2001 From: Byungho An Date: Fri, 28 Jun 2013 16:35:32 +0900 Subject: net: stmmac: fixed enh_desc set always zero This patch fixed that enh_desc value is always zero. Due to calling order of stmmac_selec_desc_mode(), enh_desc value is always zero. Even though mac is set to use enhanced dma descriptor, if enh_desc is zero, functions related dma descriptor are not working correctly.
