enum_ieee80211_key_flags - key flags SYNOPSIS
enum ieee80211_key_flags { IEEE80211_KEY_FLAG_WMM_STA, IEEE80211_KEY_FLAG_GENERATE_IV, IEEE80211_KEY_FLAG_GENERATE_MMIC, IEEE80211_KEY_FLAG_PAIRWISE, IEEE80211_KEY_FLAG_SW_MGMT }; CONSTANTS
IEEE80211_KEY_FLAG_WMM_STA Set by mac80211, this flag indicates that the STA this key will be used with could be using QoS. IEEE80211_KEY_FLAG_GENERATE_IV This flag should be set by the driver to indicate that it requires IV generation for this particular key. IEEE80211_KEY_FLAG_GENERATE_MMIC This flag should be set by the driver for a TKIP key if it requires Michael MIC generation in software. IEEE80211_KEY_FLAG_PAIRWISE Set by mac80211, this flag indicates that the key is pairwise rather then a shared key. IEEE80211_KEY_FLAG_SW_MGMT This flag should be set by the driver for a CCMP key if it requires CCMP encryption of management frames (MFP) to be done in software. DESCRIPTION
These flags are used for communication about keys between the driver and mac80211, with the flags parameter of struct ieee80211_key_conf. AUTHOR
