Split header after L4 if IPv4 not fragmented and if IPv6
does not include fragment extension header, otherwise
treat as packet type 4.

Fragment Checksum (16)
This field is used to provide the fragment checksum value for fragmented UDP packets. The Fragment
Checksum field can be used to accelerate UDP checksum verification by the host processor. This
operation is enabled by the RXCSUM.IPPCSE bit.
This field is mutually exclusive with the RSS hash. It is enabled when the RXCSUM.PCSD bit is cleared.
RSS Hash Value (32)
RSS hash value.
