Avinash Patil 47411a06c0 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.

Amitkumar Karwar 8311f0da95 mwifiex: improve error path handling in usb.c
skb allocated during initialisation is reused for receiving
commands/events by USB interface. We miss to reset skb->data in
failure cases. This patch takes care of it.

Amitkumar Karwar e80c81dc14 mwifiex: fix bugs in event handling code
This patch ensures uniformity in event skb sent by interface code
(USB/PCIe/SDIO) which automatically fixes following bugs.

1) For USB interface, same buffer is reused for receiving cmd and
events from firmware. While handling events, we perform
skb_pull(skb, 4) to remove event header. Corresponding skb_push()
call is missing while submitting the buffer.
2) For PCIe interface, event skb is passed with event header.
Recently added uAP events EVENT_UAP_STA_ASSOC, EVENT_UAP_STA_DEAUTH
will not work for PCIe, as they assume event skb points to event body.
