*
|
|
* ip_chksum_fail
|
|
* Indicates that the computed checksum did not match the
|
|
* checksum in the IP header.
|
|
*
|
|
* sa_idx_invalid
|
|
* Indicates no matching entry was found in the address search
|
|
* table for the source MAC address.
|
|
*
|
|
* da_idx_invalid
|
|
* Indicates no matching entry was found in the address search
|
|
* table for the destination MAC address.
|
|
*
|
|
* amsdu_addr_mismatch
|
|
* Indicates that an A-MSDU with 'from DS = 0' had an SA mismatching
|
|
* TA or an A-MDU with 'to DS = 0' had a DA mismatching RA
|
|
*
|
|
* rx_in_tx_decrypt_byp
|
|
* Indicates that RX packet is not decrypted as Crypto is busy
|
|
* with TX packet processing.
|
|
*
|
|
* encrypt_required
|
|
* Indicates that this data type frame is not encrypted even if
|
|
* the policy for this MPDU requires encryption as indicated in
|
|
* the peer table key type.
|
|
*
|
|
* directed
|
|
* MPDU is a directed packet which means that the RA matched
|
|
* our STA addresses. In proxySTA it means that the TA matched
|
|
* an entry in our address search table with the corresponding
|
|
* 'no_ack' bit is the address search entry cleared.
|
|
*
|
|
* buffer_fragment
|
|
* Indicates that at least one of the rx buffers has been
|
|
* fragmented. If set the FW should look at the rx_frag_info
|
|
* descriptor described below.
|
|
*
|
|
* mpdu_length_err
|
|
* Indicates that the MPDU was pre-maturely terminated
|
|
* resulting in a truncated MPDU. Don't trust the MPDU length
|
|
* field.
|
|
*
|
|
* tkip_mic_err
|
|
* Indicates that the MPDU Michael integrity check failed
|
|
*
|
|
* decrypt_err
|
|
* Indicates that the MPDU decrypt integrity check failed
|
|
*
|
|
* fcs_err
|
|
* Indicates that the MPDU FCS check failed
|
|
*
|
|
* flow_idx_timeout
|
|
* Indicates an unsuccessful flow search due to the expiring of
|
|
* the search timer.
|
|
*
|
|
* flow_idx_invalid
|
|
* flow id is not valid.
|
|
*
|
|
* decrypt_status_code
|
|
* Field provides insight into the decryption performed. Values
|
|
* are defined in enum %RX_DESC_DECRYPT_STATUS_CODE_*.
|
|
*
|
|
* rx_bitmap_not_updated
|
|
* Frame is received, but RXPCU could not update the receive bitmap
|
|
* due to (temporary) fifo constraints.
|
|
*
|
|
* msdu_done
|
|
* If set indicates that the RX packet data, RX header data, RX
|
|
* PPDU start descriptor, RX MPDU start/end descriptor, RX MSDU
|
|
* start/end descriptors and RX Attention descriptor are all
|
|
* valid. This bit must be in the last octet of the
|
|
* descriptor.
