From e2a240c7d3bcebf90936cc7c22c2729b3a4cec1f Mon Sep 17 00:00:00 2001 From: Sonic Zhang Date: Wed, 28 Aug 2013 18:55:39 +0800 Subject: driver:net:stmmac: Disable DMA store and forward mode if platform data force_thresh_dma_mode is set. Some synopsys ip implementation doesn't support DMA store and forward mode, such as BF60x. So, set force_thresh_dma_mode to use DMA thresholds only. Update document and devicetree as well.
