From 17bcb684f08649a2ab6a7dcd8288332e72d208f1 Mon Sep 17 00:00:00 2001 From: Francois Romieu Date: Mon, 23 Jul 2012 22:55:55 +0200 Subject: r8169: revert "add byte queue limit support". MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This reverts commit 036dafa28da1e2565a8529de2ae663c37b7a0060. First it appears in bisection, then reverting it solves the usual netdev watchdog problem for different people. I don't have a proper fix yet so get rid of it.
