/* * Sets the rate to duration values in MAC - used for multi- * rate retry. * The rate duration table needs to cover all valid rate codes; * the 11g table covers all ofdm rates, while the 11b table * covers all cck rates => all valid rates get covered between * these two mode's ratetables! * But if we're turbo, the ofdm phy is replaced by the turbo phy * and cck is not valid with turbo => all rates get covered * by the turbo ratetable only */
