mwifiex: Trigger a card reset on reaching tx_timeout threshold tx_timeout doesn't always lead to a cmd_timeout. There are occurrences where cmd_timeout never gets triggered for a long time and we encounter a kernel crash. In this patch, we track the consecutive timeouts (tx_timeout_cnt). When tx_timeout_cnt exceeds the threshold, trigger a card reset thereby avoiding a kernel crash.

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.

mwifiex: improve uAP RX handling 1. Separate file for uAP RX handling. 2. If received packet is broadcast/multicast, send it to kernel as well as requeue it back to uAP TX queue. 3. If received packet is for associated STA (intra-BSS), requeue it back to uAP TX queue. 4. In all other cases (packets for AP or inter-BSS packets), pass packet to kernel to handle it accordingly.

mwifiex: fix uAP TX packet timeout issue When running heavy traffic we stop the tx queue if the pending packet count reaches certain threshold. Later, the tx queue should be woken up as soon as the packet count falls below the threshold. Current code wakes TX queue up on STA interface only. Removing the check for STA interface will allow both STA and AP interfaces to resume transmit when tx_pending count becomes low.
