WO
N/A
Preload
The number of bytes to pre-load into the MAC TX FIFO before the
frame begins transmission to the PHY. This may need to be non-zero
for large IP headers that want to have the checksum inserted to ensure
the checksum is not transmitted before the end of the header is loaded.
24:16
WO
N/A
Packet ID
The 9-bit ID value used to identify this packet in the TX status FIFO.
15:10
WO
N/A
IP Header Offset
Offset in bytes to the IP header in this frame. If this value is non-zero
then the IP header checksum will be corrected.
9
WO
N/A
Append CRC
When set, the transmitter shall append the correct CRC checksum to
the end of the frame.
8
WO
N/A
Fix CRC
When set, the transmitter shall correct the existing CRC checksum on
the end of the packet.
