    bwn: fixing performance problems and an RX buffer overflow problem
    
    * Commenting a bwn_shm_write_2 call that destroys performance especially
      when sending.  This call is also commented in Linux's b43 driver.
    
    * Handling Overflows of the RX buffer in bwn by just dropping all entries.
      With 256 slots in the RX buffer this overflow will almost never happen in
      practice.
