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.
