enum ieee80211_rate_flags { IEEE80211_RATE_SHORT_PREAMBLE, IEEE80211_RATE_MANDATORY_A, IEEE80211_RATE_MANDATORY_B, IEEE80211_RATE_MANDATORY_G, IEEE80211_RATE_ERP_G, IEEE80211_RATE_SUPPORTS_5MHZ, IEEE80211_RATE_SUPPORTS_10MHZ };
IEEE80211_RATE_SHORT_PREAMBLE
Hardware can send with short preamble on this bitrate; only relevant in 2.4GHz band and with CCK rates.
IEEE80211_RATE_MANDATORY_A
This bitrate is a mandatory rate when used with 802.11a (on the 5 GHz band); filled by the core code when registering the wiphy.
IEEE80211_RATE_MANDATORY_B
This bitrate is a mandatory rate when used with 802.11b (on the 2.4 GHz band); filled by the core code when registering the wiphy.
IEEE80211_RATE_MANDATORY_G
This bitrate is a mandatory rate when used with 802.11g (on the 2.4 GHz band); filled by the core code when registering the wiphy.
IEEE80211_RATE_ERP_G
This is an ERP rate in 802.11g mode.
IEEE80211_RATE_SUPPORTS_5MHZ
Rate can be used in 5 MHz mode
IEEE80211_RATE_SUPPORTS_10MHZ
Rate can be used in 10 MHz mode
Hardware/specification flags for rates. These are structured in a way that allows using the same bitrate structure for different bands/PHY modes.
