From 5ea060a9f96740969d1d1c392e446da823bb01d3 Mon Sep 17 00:00:00 2001 From: Claudiu Manoil Date: Fri, 5 Sep 2014 13:52:46 +0800 Subject: [PATCH] net: tsec: Remove tx snooping support from LS1 Remove the DMCTRL Tx snooping bits (TDSEN and TBDSEN) as a workaround for LS1. It has been observed that currently the Tx stops functioning after a fair amount of Tx traffic with these settings on. These bits are sticky and once set they cannot be reset from Linux, for instance.
