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.
