The txrates substructure has been extended to provide different fields for different types of packets (management/data, unicast/multicast). These fields are updated on association to values compatible with the access point we are associating to. Drivers can then use the new ieee80211softmac_suggest_txrate() function call when deciding which rate to transmit each frame at. This is immensely useful for ZD1211, and bcm can use it too. The user can still specify a rate through iwconfig, which is matched for all transmissions (assuming the rate they have specified is in the rate set required by the AP). At a later date, we can incorporate automatic rate management into the ieee80211softmac_recalc_txrates() function. This patch also removes the mcast_fallback field. Sam Leffler pointed out that this field is meaningless, because no driver will ever be retransmitting mcast frames (they are not acked).
