TCP/IP/UDP Header for the Last Frame
The hardware makes the following changes to the headers of the last packet that is
derived from each TCP segmentation context.
Last frame payload bytes = PAYLEN - (N * MSS)
MAC Header (for SNAP Packets)
IPv4 Header
IPv6 Header
TCP Header
• IP Identification: incremented from last value (wrap around)
• IP Total Length = MSS + HDRLEN - IPCSS
• IP Checksum
• Payload Length = MSS + HDRLEN - IPCSS - Ipv6Size (while Ipv6Size = 40Bytes)
• Sequence Number update: Add previous TCP payload size to the previous sequence
• If FIN flag = 1b, it is cleared in these frames.
• If PSH flag =1b, it is cleared in these frames.
• TCP Checksum
• UDP Length: MSS + HDRLEN - TUCSS
• UDP Checksum
• Type/Len field = Last frame payload bytes + HDRLEN - 14
• IP Total Length = (last frame payload bytes + HDRLEN) - IPCSS
• IP Identification: incremented from last value (wrap around)
• IP Checksum
• Payload Length = last frame payload bytes + HDRLEN - IPCSS - Ipv6Size (while
• Sequence Number update: Add previous TCP payload size to the previous sequence
