From 7a8fa3e16202fc5caec6787b4f394aecca7dc17a Mon Sep 17 00:00:00 2001 From: Rajkumar Manoharan Date: Fri, 29 Apr 2011 14:48:45 +0530 Subject: [PATCH] mac80211: use wake_queue to restart trasmit commit 470ab2a23b453518ac86937572b4531d8925ca55 upstream. netif_tx_start_all_queues is used to allow the upper layer to transmit frames but it does not restart transmission. To restart the trasmission use netif_tx_wake_all_queues. Not doing so, sometimes stalls the transmission and the application has to be restarted to proceed further. This issue was originally found while sending udp traffic in higer bandwidth in open environment without bgscan. Signed-off-by: Rajkumar Manoharan Signed-off-by: John W.
