NAME

       cfg80211_rx_mgmt - notification of received, unprocessed management frame

SYNOPSIS

       bool cfg80211_rx_mgmt(struct wireless_dev * wdev, int freq, int sig_dbm, const u8 * buf, size_t len, gfp_t gfp);

ARGUMENTS

       wdev
	   wireless device receiving the frame

       freq
	   Frequency on which the frame was received in MHz

       sig_dbm
	   signal strength in mBm, or 0 if unknown

       buf
	   Management frame (header + body)

       len
	   length of the frame data

       gfp
	   context flags

DESCRIPTION

       This function is called whenever an Action frame is received for a station mode interface, but is not processed in kernel.

RETURN

       true if a user space application has registered for this frame. For action frames, that makes it responsible for rejecting unrecognized
       action frames; false otherwise, in which case for action frames the driver is responsible for rejecting the frame.

CONSTANTS

       RX_FLAG_MMIC_ERROR
	   Michael MIC error was reported on this frame. Use together with RX_FLAG_MMIC_STRIPPED.

       RX_FLAG_DECRYPTED
	   This frame was decrypted in hardware.

       RX_FLAG_MMIC_STRIPPED
	   the Michael MIC is stripped off this frame, verification has been done by the hardware.

       RX_FLAG_IV_STRIPPED
	   The IV/ICV are stripped from this frame. If this flag is set, the stack cannot do any replay detection hence the driver or hardware
	   will have to do that.

       RX_FLAG_FAILED_FCS_CRC
	   Set this flag if the FCS check failed on the frame.

       RX_FLAG_FAILED_PLCP_CRC
	   Set this flag if the PCLP check failed on the frame.

       RX_FLAG_MACTIME_START
	   The timestamp passed in the RX status (mactime field) is valid and contains the time the first symbol of the MPDU was received. This is
	   useful in monitor mode and for proper IBSS merging.

       RX_FLAG_SHORTPRE
	   Short preamble was used for this frame

       RX_FLAG_HT
	   HT MCS was used and rate_idx is MCS index

       RX_FLAG_40MHZ
	   HT40 (40 MHz) was used

       RX_FLAG_SHORT_GI
	   Short guard interval was used

       RX_FLAG_NO_SIGNAL_VAL
	   The signal strength value is not present. Valid only for data frames (mainly A-MPDU)

       RX_FLAG_HT_GF
	   This frame was received in a HT-greenfield transmission, if the driver fills this value it should add IEEE80211_RADIOTAP_MCS_HAVE_FMT
	   to hw.radiotap_mcs_details to advertise that fact

       RX_FLAG_AMPDU_DETAILS
	   A-MPDU details are known, in particular the reference number (ampdu_reference) must be populated and be a distinct number for each
	   A-MPDU

       RX_FLAG_AMPDU_REPORT_ZEROLEN
	   driver reports 0-length subframes

       RX_FLAG_AMPDU_IS_ZEROLEN
	   This is a zero-length subframe, for monitoring purposes only

       RX_FLAG_AMPDU_LAST_KNOWN
	   last subframe is known, should be set on all subframes of a single A-MPDU

       RX_FLAG_AMPDU_IS_LAST
	   this subframe is the last subframe of the A-MPDU

       RX_FLAG_AMPDU_DELIM_CRC_ERROR
	   A delimiter CRC error has been detected on this subframe

       RX_FLAG_AMPDU_DELIM_CRC_KNOWN
	   The delimiter CRC field is known (the CRC is stored in the ampdu_delimiter_crc field)

       RX_FLAG_MACTIME_END
	   The timestamp passed in the RX status (mactime field) is valid and contains the time the last symbol of the MPDU (including FCS) was
	   received.

       RX_FLAG_VHT
	   VHT MCS was used and rate_index is MCS index

       RX_FLAG_80MHZ
	   80 MHz was used

       RX_FLAG_80P80MHZ
	   80+80 MHz was used

       RX_FLAG_160MHZ
	   160 MHz was used

DESCRIPTION

       These flags are used with the flag member of struct ieee80211_rx_status.
