As it should be possible to provide data in message towards the

from the device, before processing the individual bss entries.
This error condition is only applicable when the list contains
entries. A specific scan, ie. for a specific ssid, can result
in a scan completion without finding any bss entries. No need
to flag it as an error in the log when this happens.

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.

When command timeout happens due to a bug in firmware/hardware,
the timeout handler just prints some debug information. User is
unable to reload the driver in this case.

Inspired by 9a821f5d "libertas: add sd8686 reset_card support",
this patch adds card reset support for SDIO interface when
command timeout happens. If the SDIO host contoller supports
MMC_POWER_OFF|UP|ON operations, the chip will be reset and the
firmware will be re-downloaded.

Realtek devices with designation RTL8188CE-VL have the so-called B-cut
of the wireless chip. This patch adds the special programming needed by
these devices. In addition, a variable that was static has been moved into
the private data area as it is now needed in two different routines. This
change also fixes a minor bug that would be present if a system had more
than one RTL81{88,92}CE devices. Other drivers in the rtlwifi family had
already made this change, thus the variable already exists in the private
data structure.
