From 47411a06c0c44b3c9dc2feffb0d97785ec9aaa68 Mon Sep 17 00:00:00 2001 From: Avinash Patil Date: Thu, 1 Nov 2012 18:44:16 -0700 Subject: mwifiex: add multi-queue support This patch adds support for multiple TX queues inside mwifiex driver. Four different queues according to WMM access categories are defined for each virtual interface. When a packet is received from netdev for transmission, tx pending count for particular queue is incremented and if tx pending count has reached upper water-mark, this queue is stopped instead of stopping all queues. Similarly when a packet is successfully transmitted from device, tx pending count is decremented per queue and if pending count falls below lower water-mark, queue operations are again resumed. This ensures that not all tranmission is blocked if traffic with particular TOS value suddenly increases. Also wake all queues after association/IBSS_join/uAP_BSS_start to enable traffic on all queues. Signed-off-by: Avinash Patil Signed-off-by: Bing Zhao Signed-off-by: John W.
