Log:
  If frames are dumped out of the queue, let's at least see what they are.
  
  This shows that the majority of the weird traffic I see here are probe
  frames that haven't been sent out, but I can also trigger this condition
  by doing ICMP w/ -i 0.3 - enough to trigger the TX during actual scanning,
  but not fast enough to stop scanning from occuring.
