Michael MIC error was reported on this frame.
Use together with RX_FLAG_MMIC_STRIPPED
.
This frame was decrypted in hardware.
The timestamp passed in the RX status (mactime
field) is valid and contains the time the SYNC preamble was received.
the Michael MIC is stripped off this frame, verification has been done by the hardware.
The IV and 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.
Set this flag if the FCS check failed on the frame.
Set this flag if the PCLP check failed on the frame.
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.
The signal strength value is not present. Valid only for data frames (mainly A-MPDU)
A-MPDU details are known, in particular the reference
number (ampdu_reference
) must be populated and be a distinct number for
each A-MPDU
Currently only valid for CCMP/GCMP frames, this
flag indicates that the PN was verified for replay protection.
Note that this flag is also currently only supported when a frame
is also decrypted (ie. RX_FLAG_DECRYPTED
must be set)
The driver should set this flag if it did de-duplication by itself.
last subframe is known, should be set on all subframes of a single A-MPDU
this subframe is the last subframe of the A-MPDU
A delimiter CRC error has been detected on this subframe
The delimiter CRC field is known (the CRC
is stored in the ampdu_delimiter_crc
field)
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.
Report frame only to monitor interfaces without processing it in any regular way. This is useful if drivers offload some frames but still want to report them for sniffing purposes.
Process and report frame to all interfaces except monitor interfaces. This is useful if drivers offload some frames but still want to report them for sniffing purposes.
Some drivers may prefer to report separate A-MSDU subframes instead of a one huge frame for performance reasons. All, but the last MSDU from an A-MSDU should have this flag set. E.g. if an A-MSDU has 3 frames, the first 2 must have the flag set, while the 3rd (last) one must not have this flag set. The flag is used to deal with retransmission/duplication recovery properly since A-MSDU subframes share the same sequence number. Reported subframes can be either regular MSDU or singly A-MSDUs. Subframes must not be interleaved with other frames.
This frame contains vendor-specific radiotap data in the skb->data (before the frame) as described by the struct ieee80211_vendor_radiotap.
The mic was stripped of this packet. Decryption was done by the hardware
Allow the same PN as same packet before. This is used for AMSDU subframes which can have the same PN as the first subframe.
The ICV is stripped from this frame. CRC checking must be done in the hardware.
