NAME
enum_mac80211_rx_flags - receive flagsSYNOPSIS
enum mac80211_rx_flags { RX_FLAG_MMIC_ERROR, RX_FLAG_DECRYPTED, RX_FLAG_RADIOTAP, RX_FLAG_MMIC_STRIPPED, RX_FLAG_IV_STRIPPED, RX_FLAG_FAILED_FCS_CRC, RX_FLAG_FAILED_PLCP_CRC, RX_FLAG_TSFT, RX_FLAG_SHORTPRE, RX_FLAG_HT, RX_FLAG_40MHZ, RX_FLAG_SHORT_GI };
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_RADIOTAP
- This frame starts with a radiotap header.
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_TSFT
- The timestamp passed in the RX status (mactime field) is valid. This is useful in monitor mode and necessary for beacon frames to enable 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
DESCRIPTION
These flags are used with the flag member of struct ieee80211_rx_status.
