broadcast mac address.
This patch adds a check to avoid checking availability of

On some platforms, system goes out of memory during heavy
Rx traffic with our USB chipsets.
In case of SDIO/PCIe, after receiving 50 packets in Rx queue
we stop processing interrupts till packets pending fall below
low threshold i.e 20. We don't have similar logic for USB,
so if host platform is slow, we would hit a case where firmware
keeps on pushing packets at high speed than driver/kernel can
process.
We will stop submitting URBs for Rx data when pending packet
count reaches high threshold and restart them when enough
packets are consumed to solve the problem.

Disconnect flow may be invoked either from upper layer request,
or from event reported by the firmware.
In case of firmware event, driver need to release resources for the station but
not send another disconnect WMI command.
In case of upper layer request, WMI_DISCONNECT_STA_CMDID command need to
be issued for the firmware to perform disconnect on the MAC layer. Eventually,
event is expected to confirm MAC disconnect, but it is better to not wait for
firmware event and release station resources immediately. FW may fail to
report disconnect for various reasons, so one could not rely on event always reported.
Introduce parameter to distinguish 2 cases above to prevent double WMI command
issuing.
