CMD_MAC_CONTROL is currently sent async to the firmware, and is sent
from the lbs_setup_firmware() path during device init.
This means that device init can complete with commands pending, and
the if_sdio driver will sometimes power down the device (after init)
with this command still pending.
This was causing an occasional spurious command timeout after init,
leading to a device reset.
Fix this by making CMD_MAC_CONTROL synchronous when called from the
lbs_setup_firmware() path.

"adapter->bss_prio_tbl[j].bss_prio_head" points to linked list of
interfaces with priority 'j'. "bss_prio_tbl[j].bss_prio_cur" is
supposed to point to next interface every time the routine for
dequeuing the packet is called. This ensures that each interface
gets fair chance.
Currently we have AP and station interfaces with priority '0'.
Therefore "adapter->bss_prio_tbl[0].bss_prio_cur" should
alternately point to AP and station nodes. Since "bss_prio_cur"
is not correctly updated, for each packet picked for AP, two
packets are picked for station interface.
This patch fixes the problem by correctly updating "bss_prio_cur".

Currently AP interface has higher priority over station. Hence
separate entries are created in "adapter->bss_prio_tbl" for these
interfaces and station packet is dequeued only if there is not
packet in queue for AP. It is observed that ping for station
interface doesn't work if heavy traffic is running on AP.
The problem is fixed by having same priority for both the
interfaces. This patch also removes an extra initialisation
for "priv->bss_priority".

*Remove all the checks that will be handled by cfg80211
based on the interface combination advertised. For instance,
driver supports at the maximum 8 beaconing interface, while
we advertise maximum 8 beaconing interface in the interface
combination support.
*cfg80211 will take care of not allowing
us to add an interface that is not supported by the
driver, further if the change_interface changes the
old interface to a beaconing interface while we had
reached the max limit of 8 beaconing interface, again
cfg80211 takes care of this stuff!
So remove all these checks.

position.

gcc 4.8 warns for this memcpy. While the copy size is correct, the whole
copy seems to be a nop because the destination is never used, and
there's no need to use memcpy to copy pointers anyways. And the
type of the pointer was wrong, but at least those are always the same.
Just remove it.

Instead of allocating one big chunk of DMA-coherent
memory for the firmware and keeping it around, only
vmalloc() the firmware and copy it into a single
page of DMA-coherent memory for the upload.
The advantage is that we don't need DMA memory for
the firmware image that is stored while the driver
is operating, we only need it while uploading.
This will make it easier for the driver to work if
the system has fragmented memory.
