Empty, written by the FEC (=0) and user (=1).
0 The data buffer associated with this BD has been filled with received data or data reception has been aborted due
1 The data buffer associated with this BD is empty or reception is currently in progress.
Receive software ownership bit
This field is reserved for use by software. This read/write bit must not be modified by hardware. Its value does not
affect hardware.
Wrap, written by user.
0 The next buffer descriptor is found in the consecutive location
1 The next buffer descriptor is found at the location defined in R_DES_START.
Receive software ownership bit
This field is reserved for use by software. This read/write bit must not be modified by hardware. Its value does not
affect hardware.
Last in frame, written by the FEC.
0 The buffer is not the last in a frame.
1 The buffer is the last in a frame.
Miss, written by the FEC.
This bit is set by the FEC for frames that were accepted in promiscuous mode, but were flagged as a miss by the
internal address recognition. Therefore, while in promiscuous mode, you can use the M bit to determine whether the
frame was destined to this station. This bit is valid only if the L and the PROM bits are set.
0 The frame was received because of an address recognition hit.
1 The frame was received because of promiscuous mode.
Set if the DA is broadcast (FF-FF-FF-FF-FF-FF).
Set if the DA is multicast and not broadcast.
RX frame length violation, written by the FEC.
A frame length greater than ETH_R_CNTRL[MAX_FL] was recognized. This bit is valid only if the L bit is set. The
receive data is not altered in any way unless the length exceeds 2047 bytes.
RX non-octet aligned frame, written by the FEC.
A frame that contains a number of bits not divisible by 8 was received, and the CRC check that occurred at the
preceding byte boundary generated an error. This bit is valid only if the L bit is set. If this bit is set, the CR bit is not set.
RX CRC error, written by the FEC.
This frame contains a CRC error and is an integral number of octets in length. This bit is valid only if the l bit is set.
to an error condition. The status and length fields have been updated as required.
