    [PATCH] softmac: suggest per-frame-type TX rate · 8462fe3c
    Daniel Drake authored
    This patch is the first step towards rate control inside softmac.
    
    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).
