* Indicates the first MSDU of the PPDU . If both first_mpdu
* and last_mpdu are set in the MSDU then this is a not an
* A - MPDU frame but a stand alone MPDU . Interior MPDU in an
* A - MPDU shall have both first_mpdu and last_mpdu bits set to
* 0 . The PPDU start status will only be valid when this bit
* is set .
*

* Multicast / broadcast indicator . Only set when the MAC
* address 1 bit 0 is set indicating mcast / bcast and the BSSID
* matches one of the 4 BSSID registers . Only set when
* first_msdu is set .

* control field is set . Only set when first_msdu is set .
*
* a_msdu_error
* Set if number of MSDUs in A - MSDU is above a threshold or if the
* size of the MSDU is invalid . This receive buffer will contain
* all of the remainder of MSDUs in this MPDU w / o decapsulation .
*
* fragment
* Indicates that this is an 802 . 11 fragment frame . This is
* set when either the more_frag bit is set in the frame
* control or the fragment number is not zero . Only set when
* first_msdu is set .

* 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

* an entry in our address search table with the corresponding
* ' no_ack ' bit is the address search entry cleared .
*

*
* rx_bitmap_not_updated
* Frame is received , but RXPCU could not update the receive bitmap
* due to ( temporary ) fifo constraints .
*

*
* overflow_err
* RXPCU Receive FIFO ran out of space to receive the full MPDU .
* Therefore this MPDU is terminated early and is thus corrupted .

*
* rxdma0_destination_ring
* rxdma1_destination_ring
* The ring to which RXDMA0 / 1 shall push the frame , assuming
