adrian 660416c5ae Introduce the CLRDMASK gating based on tid->clrdmask, enabling filtered
frames to occur.

* Create a new function which will set the bf_flags CLRDMASK bit
  if required.
* For raw frames, always set CLRDMASK.
* For BAR, ADDBA frames, always set CLRDMASK.
* For everything else, check if CLRDMASK needs to be set before
  calling tx_setds() or tx_setds11n().
* When unpausing a queue or drain/resetting it, set tid->clrdmask=1
  just to ensure traffic starts flowing.

What I need to do:

* Modify that function to _clear_ the CLRDMASK if it's not required,
  or retried frames may have CLRDMASK set when they don't need to.
  (Which isn't a huge deal, but..)

Whilst I'm here:

* ath_tx_normal_xmit() should really act like the AMPDU session TX
  functions - any incomplete frames will end up being assigned
  ath_tx_normal_comp() which will decrement tid->hwq_depth - but that
  won't have been incremented.

  So whilst I'm here, add a comment to do that.

* Fix the debug print function to be slightly clearer about things;
  it's not a good sign when I can't interpret my own debugging output.

I've done some testing on AR9280/AR5416/AR9160 STA and AP modes.
