In 'mwifiex_get_ver_ext', we have:

BCM53573 seems to be the first series of Northstar family with wireless
on the chip. The base models are BCM53573-s (A0, A1) and there is also
BCM47189B0 which seems to be some small modification.

The only problem with these chipsets seems to be watchdog. It's totally
unavailable on 53573A0 / 53573A1 and preferable PMU watchdog is broken
on 53573B0 / 53573B1.

It's been observed that firmware sends RADAR detected event without
specifying bss_num/bss_type. Also, the event body is empty.
Currently the event is being ignored by driver.

This patch checks on which interface 11H is active, accordingly fills
bss_num/bss_type and handles the event. Condition
"if (le32_to_cpu(rdr_event->passed))" which always fails is also removed.

Every active TXQ is assigned to a TID given through the
SCD_CONFIG_CMD, and acts as an identifier in the FW. However,
there may be cases this ownership needs to be changed.

For example, in the following scenario:
 1. TID x is owner of a queue
 2. Due to a shortage of queues, TID y and z share with x
 3. TID x becomes inactive and needs to be removed from the
    shared queue.
In this scenario, if another queue is freed and traffic on x
continues, we can't allocate it a new queue as long as it is
the owner of the first queue.

Support moving ownership of a TXQ to a different TID (same
STA) without stopping the queue.
