Description

Receive Accelerator Function Configuration

Fields

PADREM

Enable Padding Removal For Short IP Frames

0 (0): Padding not removed.

1 (1): Any bytes following the IP payload section of the frame are removed from the frame.

IPDIS

Enable Discard Of Frames With Wrong IPv4 Header Checksum

0 (0): Frames with wrong IPv4 header checksum are not discarded.

1 (1): If an IPv4 frame is received with a mismatching header checksum, the frame is discarded. IPv6 has no header checksum and is not affected by this setting. Discarding is only available when the RX FIFO operates in store and forward mode (RSFL cleared).

PRODIS

Enable Discard Of Frames With Wrong Protocol Checksum

0 (0): Frames with wrong checksum are not discarded.

1 (1): If a TCP/IP, UDP/IP, or ICMP/IP frame is received that has a wrong TCP, UDP, or ICMP checksum, the frame is discarded. Discarding is only available when the RX FIFO operates in store and forward mode (RSFL cleared).

LINEDIS

Enable Discard Of Frames With MAC Layer Errors

0 (0): Frames with errors are not discarded.

1 (1): Any frame received with a CRC, length, or PHY error is automatically discarded and not forwarded to the user application interface.

SHIFT16

RX FIFO Shift-16

0 (0): Disabled.

1 (1): Instructs the MAC to write two additional bytes in front of each frame received into the RX FIFO.
