VLAN control word valid.
0 Ignore VLCTL field.
1 If VLAN tag insertion is enabled for eTSEC, use the VLCTL field as the VLAN control word.
Layer 3 header is an IP header.
0 Ignore layer 3 and higher headers.
1 Assume that the layer 3 header is an IPv4 or IPv6 header, and take L3OS field as valid.
IP header is IP version 6. Valid only if IP = 1.
0 IP header version is 4.
1 IP header version is 6.
Layer 4 header is a TCP or UDP header.
0 Do not process any layer 4 header.
1 Assume that the layer 4 header is either TCP or UDP (see UDP bit), and offload checksumming
UDP protocol at layer 4.
0 Layer 4 protocol is either TCP (if TUP = 1) or undefined.
1 Layer 4 protocol is UDP if TUP = 1.
Checksum IP header enable.
0 Do not generate an IP header checksum.
1 Generate an IPv4 header checksum.
Checksum TCP or UDP header enable.
0 Do not generate a TCP or UDP header checksum. RFC 768 advises that UDP packets not
1 Generate a TCP header checksum if IP = 1 and TUP = 1 and UDP = 0.
Disable calculation of TCP or UDP pseudo-header checksum. This bit should be set if IP options
need to be consulted in forming the pseudo-header checksum, as eTSEC does not examine IP
options or extension headers for TCP/IP offload on transmit.
0 Calculate TCP or UDP pseudo-header checksum as normal, assuming that the IP header has
1 Do not calculate a TCP or UDP pseudo-header checksum, but instead use the value in field
Reserved
Layer 4 header offset from start of layer 3 header. The layer 4 header starts L4OS octets after the
layer 3 header if it is present. The maximum layer 3 header length supported is thus 255 bytes,
which may prevent TCP/IP offload on particularly large IPv6 headers.
Layer 3 header offset from start of frame not including the 8 bytes for this FCB. The layer 3 header
starts L3OS octets from the start of the frame including any custom preamble header that may be
present. The maximum layer 2 header length supported is thus 255 bytes.
Pseudo-header checksum (16-bit one’s complement sum with carry wraparound, but without result
inversion) for TCP or UDP packets, calculated by software. Valid only if NPH = 1.
VLAN control word for insertion in the transmitted VLAN tag. Valid only if VLN = 1.
on the basis that the IP header has no extension headers.
