  Log:
  SVN rev 218932 on 2011-02-22 00:37:53Z by adrian
  
  Shuffle around the RTS/CTS rate/duration logic.
  
  * Turn ath_tx_calc_ctsduration() into a function that
    returns the ctsduration, or -1 for HT rates;
  * add a printf() to ath_tx_calc_ctsduration() which will be
    very loud if somehow that function is called with an MCS
    rate;
  * Add ath_tx_get_rtscts_rate() which returns the RTS/CTS
    rate to use for the given data rate, incl. the short
    preamble flag;
  * Only call ath_tx_calc_ctsduration() for non-11n chipsets;
    11n chipsets don't require the rtscts duration to be
    calculated.
