Constants

IEEE80211_RX_IN_SCAN

received while scanning

IEEE80211_RX_RA_MATCH

frame is destined to interface currently processed (incl. multicast frames)

IEEE80211_RX_FRAGMENTED

fragmented frame

IEEE80211_RX_AMSDU

a-MSDU packet

IEEE80211_RX_MALFORMED_ACTION_FRM

action frame is malformed

IEEE80211_RX_DEFERRED_RELEASE

frame was subjected to receive reordering

Description

These are per-frame flags that are attached to a frame in the rx_flags field of struct ieee80211_rx_status.

enum ieee80211_rx_flags

enum ieee80211_rx_flags {
IEEE80211_RX_CMNTR,
IEEE80211_RX_BEACON_REPORTED
};

Constants

IEEE80211_RX_CMNTR

received on cooked monitor already

IEEE80211_RX_BEACON_REPORTED

This frame was already reported to cfg80211_report_obss_beacon.

Description

These flags are used across handling multiple interfaces for a single frame.

enum work_done_result

enum work_done_result {
WORK_DONE_DESTROY,
WORK_DONE_REQUEUE
};

Constants

WORK_DONE_DESTROY

This work item is no longer needed, destroy.

WORK_DONE_REQUEUE

This work item was reset to be reused, and should be requeued.

IEEE80211_SDATA_ALLMULTI,

IEEE80211_SDATA_DISCONNECT_RESUME,
IEEE80211_SDATA_IN_DRIVER
};

Constants

IEEE80211_SDATA_ALLMULTI

interface wants all multicast packets

IEEE80211_SDATA_PROMISC

interface is promisc

IEEE80211_SDATA_OPERATING_GMODE

operating in G-only mode

IEEE80211_SDATA_DONT_BRIDGE_PACKETS

bridge packets between associated stations and deliver multicast frames both back to wireless media and to the local net stack.

IEEE80211_SDATA_DISCONNECT_RESUME

Disconnect after resume.

IEEE80211_SDATA_IN_DRIVER

indicates interface was added to driver

---

enum ieee80211_sdata_state_bits

enum ieee80211_sdata_state_bits {
SDATA_STATE_RUNNING,
SDATA_STATE_OFFCHANNEL
};

Constants

SDATA_STATE_RUNNING

virtual interface is up & running; this mirrors netif_running but is separate for interface type change handling while the interface is up

SDATA_STATE_OFFCHANNEL

This interface is currently in offchannel mode, so queues are stopped

---

enum mac80211_scan_state

enum mac80211_scan_state {
SCAN_DECISION,
SCAN_SET_CHANNEL,
SCAN_SEND_PROBE,
SCAN_SUSPEND,
SCAN_RESUME
};

Constants

SCAN_DECISION

Main entry point to the scan state machine, this state determines if we should keep on scanning or switch back to the operating channel

SCAN_SET_CHANNEL

Set the next channel to be scanned

SCAN_SEND_PROBE

Send probe requests and wait for probe responses

SCAN_SUSPEND

Suspend the scan and go back to operating channel to send out data

SCAN_RESUME

Resume the scan and scan the next channel
