The ready message from the target could be processed
before the host HW init has completed. In this case,
htc_process_target_rdy() would assume the target has timed
out, when it hasn't. Fix this by checking if the target
has sent the ready message properly.

The current way of managing beaconing in ad-hoc
mode has a subtle race - the beacon obtained from mac80211
is freed in the SWBA handler rather than the TX
completion routine. But transmission of beacons goes
through the normal SKB queue maintained in hif_usb,
leading to a situation where __skb_dequeue() in the TX
completion handler goes kaput.
Fix this by simply getting a beacon from mac80211 for
every SWBA and free it in its completion routine.

When the USB device has been unplugged, there is
no point in trying to send commands to the target.
Fix this by denying all WMI commands in such a case.

This patch adds support for writing multiple registers
in a single USB command.
Specific calls from the HW code that performs multiple
register writes would be modified to make use of this
in subsequent patches.

Set IEEE80211_HW_RX_INCLUDES_FCS to indicate that
the FCS is present in RX frames. Also, remove a redundant
assignment of skb length and include the FCS_LEN
when checking padding.
Fixing this issue makes TKIP work.

Not setting the opmode properly during initialization
results in the firmware sending up a bunch of packets
before add_interface() has been called, for the first
interface.
This patch fixes the issue by setting the initial mode
to 'managed'.

Stop/restart TX queues when the internal SKB
queue is full. This helps handle TX better
under heavy load.
