From cce1fa36a8ed36e8a3f64455e2a830f48e904c64 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Thu, 10 May 2007 14:11:16 -0700 Subject: [PATCH] [NET_SCHED]: Reread dev->qdisc for NETDEV_TX_OK Now that we return the queue length after NETDEV_TX_OK we better make sure that we have the right queue. Otherwise we can cause a stall after a really quick dev_deactive/dev_activate. Signed-off-by: Herbert Xu Signed-off-by: David S.
