ENUM MAC80211_RX_FLA(9) The basic mac80211 driver inte ENUM MAC80211_RX_FLA(9)

NAME enum_mac80211_rx_flags - receive flags

SYNOPSIS enum mac80211_rx_flags { RX_FLAG_MMIC_ERROR, RX_FLAG_DECRYPTED, RX_FLAG_MMIC_STRIPPED, RX_FLAG_IV_STRIPPED, RX_FLAG_FAILED_FCS_CRC, RX_FLAG_FAILED_PLCP_CRC, RX_FLAG_MACTIME_MPDU, 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_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_MPDU 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

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