From d723485cb4ca9eefaf43fd9f165554094b97f2c2 Mon Sep 17 00:00:00 2001 From: Jon Mason Date: Sat, 19 Jan 2013 02:02:32 -0700 Subject: ntb_netdev: remove tx timeout There is a race between disabling and enabling the tx queue, resulting in tx timeouts. Since all the tx timeout does is re-enable the tx queue, simple remove the start/stop of the queue and the tx timeout routine.
