Definition at line 110 of file ieee80211.h.
| #define IEEE80211_STYPE_ASSOC_REQ 0x0000 |
Subtype value for association-request management frames.
Association request frames are sent after authentication from the client to the Access Point to establish the client as part of the Access Point's network.
Definition at line 118 of file ieee80211.h.
| #define IEEE80211_STYPE_ASSOC_RESP 0x0010 |
Subtype value for association-response management frames.
Association response frames are sent by the Access Point to confirm or deny the association requested in an association request frame.
Definition at line 125 of file ieee80211.h.
| #define IEEE80211_STYPE_REASSOC_REQ 0x0020 |
Subtype value for reassociation-request management frames.
Reassociation request frames are sent by clients wishing to change from one Access Point to another while roaming within the same extended network (same ESSID).
Definition at line 133 of file ieee80211.h.
| #define IEEE80211_STYPE_REASSOC_RESP 0x0030 |
Subtype value for reassociation-response management frames.
Reassociation response frames are sent by the Access Point to confirm or deny the swap requested in a reassociation request frame.
Definition at line 141 of file ieee80211.h.
| #define IEEE80211_STYPE_PROBE_REQ 0x0040 |
Subtype value for probe-request management frames.
Probe request frames are sent by clients to request that all Access Points on the sending channel, or all belonging to a particular ESSID, identify themselves by BSSID, supported transfer rates, RF configuration, and other capabilities.
Definition at line 150 of file ieee80211.h.
| #define IEEE80211_STYPE_PROBE_RESP 0x0050 |
Subtype value for probe-response management frames.
Probe response frames are sent by Access Points in response to probe request frames, providing the requested information.
Definition at line 157 of file ieee80211.h.
| #define IEEE80211_STYPE_BEACON 0x0080 |
Subtype value for beacon management frames.
Beacon frames are sent by Access Points at regular intervals, usually ten per second, on the channel on which they communicate. They can be used to probe passively for access points on a channel where local regulatory restrictions prohibit active scanning, or due to their regularity as a mechanism to determine the fraction of packets that are being dropped.
Definition at line 168 of file ieee80211.h.
| #define IEEE80211_STYPE_DISASSOC 0x00A0 |
Subtype value for disassociation management frames.
Disassociation frames are sent by either a client or an Access Point to unequivocally terminate the association between the two. They may be sent by clients upon leaving the network, or by an Access Point upon reconfiguration, among other reasons; they are usually more "polite" than deauthentication frames.
Definition at line 178 of file ieee80211.h.
| #define IEEE80211_STYPE_AUTH 0x00B0 |
Subtype value for authentication management frames.
Authentication frames are exchanged between a client and an Access Point before association may be performed. Confusingly, in the most common authentication method (Open System) no security tokens are exchanged at all. Modern 802.11 security handshaking takes place after association.
Definition at line 188 of file ieee80211.h.
| #define IEEE80211_STYPE_DEAUTH 0x00C0 |
Subtype value for deauthentication management frames.
Deauthentication frames are sent by either a client or an Access Point to terminate the authentication (and therefore also the association) between the two. They are generally more forceful than disassociation frames, sent for such reasons as a failure to set up security properly after associating.
Definition at line 198 of file ieee80211.h.
| #define IEEE80211_STYPE_ACTION 0x00D0 |
Subtype value for action management frames.
Action frames are used to implement spectrum management and QoS features that iPXE currently does not support.

802.11 Frame Control field: Power Managed flag
This is set on any frame sent by a low-power station that will go into a power-saving mode immediately after this frame. Access Points are not allowed to act as low-power stations.

| #define IEEE80211_FC_MORE_DATA 0x2000 |
802.11 Frame Control field: More Data flag
This is set on any frame sent by a station that has more data queued to be sent than is in the frame.

| #define IEEE80211_FC_PROTECTED 0x4000 |
802.11 Frame Control field: Protected flag
This is set on frames in which data is encrypted (by any method).
