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.Tx PTP
packet identification number. This number will be copied into the Tx PTP packet timestamp
identification field. PTP field takes precedence over VLN field.
