NAME
       enum_ieee80211_rate_flags - rate flags

SYNOPSIS
       enum ieee80211_rate_flags {
	 IEEE80211_RATE_SHORT_PREAMBLE,
	 IEEE80211_RATE_MANDATORY_A,
	 IEEE80211_RATE_MANDATORY_B,
	 IEEE80211_RATE_MANDATORY_G,
	 IEEE80211_RATE_ERP_G
       };

CONSTANTS
       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.

DESCRIPTION
       Hardware/specification flags for rates. These are structured in a way that allows using the same bitrate structure for different bands/PHY
       modes.
