    kernel - Fix double-free in if_ath, fix lost rcvif.
    
    * Reassign rcvif in ieee80211_vap_pkt_send_dest() prior to calling
      ic_transmit().  The rcvif assignment can get lost from packet
      manipulation above that section of code.
    
    * Fix a double-free in if_ath in the error path for ath_transmit().
      Callers of ic_transmit (aka ath_transmit in this case) expect the
      mbuf to remain intact on a non-zero error return.
    
    * Document confusing code in WPI.
