|
*
|
|
* encrypt_required
|
|

|
|
* 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

*
|
|
* rx_bitmap_not_updated
|
|
* Frame is received, but RXPCU could not update the receive bitmap

|
|
* unsup_ktype_short_frame
|
|
* This bit will be '1' when WEP or TKIP or WAPI key type is

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

*
|
|
* This MPDU will not be ACKed.

|
|
*
|
|
* pn_fields_contain_valid_info
|
|
* Set by RX CRYPTO to indicate that there is a valid PN field
|

|
|
* Set by RXPCU when there is an FCS error detected for this MPDU.

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