IP and Higher Layers Frame Format
extension headers, which can be inserted between the IPv6 header and the protocol header,
shifting the protocol header accordingly. The accelerator currently only supports IPv6
without extension headers (that is, next header identifies TCP or UDP or ICMP protocol).
The most significant bit is bit 31 in the following figure. The first byte sent/received is the
leftmost byte of the first word (that is, Version/Traffic class fields).
26.3.5.5 ICMP Datagram Format
Following the IP Header, an Internet Control Message Protocol (ICMP) datagram is found
when the protocol identifier has a decimal value of 1. The ICMP datagram has 4 octets
header followed by the additional message data.
