    mac80211: adding mac80211_tx_control_flags and HT flags · 11f4b1ce
    Ron Rindjunsky 提交于
    This patch makes enum from the defines previously dwelled inside
    ieee80211_tx_control for better readability.
    The patch also addes HT flags, for 802.11n drivers:
    - IEEE80211_TXCTL_OFDM_HT: request low-level driver to use HT OFDM rates
    - IEEE80211_TXCTL_GREEN_FIELD: use green field protection
    - IEEE80211_TXCTL_DUP_DATA: duplicate data on both 20 Mhz channels
    - IEEE80211_TXCTL_40_MHZ_WIDTH: send this frame in 40Mhz width
    - IEEE80211_TXCTL_SHORT_GI: send this frame with short guard interval
    
    Tx command can be a combination of any of these flags, along with
    bitrate represented by ieee80211_rate. this will allow legacy drivers to
    switch easily to any 11n rate representation.
