I see three options to achieve this:

1) Use ieee80211_stop_queues() in ->configure_filter() and
   ieee80211_wake_queues() at the end of the workqueue function.

2) Throw away all packets until the workqueue function
   terminates.

3) Implement our own tx queue.

I prefer to do option (1) because it wouldn't require adding
additional fields to our private structure beside the work_struct
for the workqueue function, it is simple to implement and it would
not throw away any packets. Are there any side effects that I have
overlooked?

I think Michael says it's currently buggy if called outside of ->tx().
