Hardware offload layer 4 packet type.

Only a small number of DPDK drivers categorise; mostly Intel's, Mellanox's and Cisco's.

If those that do, not all of these values may be supported by the driver, althought TCP, UDP and Fragmented seem to be supported by all of them.

In this case, DPDK drivers categorise as OtherNotAFragment.

If the packet is a tunneled packet, then this is known as the Outer Layer 4 packet type.

Variants

UncategorisedOrAbsent

Either the driver did not categorise this packet or the layer 4 data structure is absent.

TransmissionControlProtocol

Transmission Control Protocol (TCP).

UserDatagramProtocol

User Datagram Protocol (UCP).

StreamControlTransmissionProtocol

Stream Control Transmission Protocol (SCTP).

InternetControlMessageProtocol

Internet Control Message Protocol (ICMP).

Only used on networks supporting internet protocol (IP) version 4.

Fragmented

A fragmented internet protocol (IP) version 4 or version 6 packet.

Will never be the first fragment.

May not necessarily be a fragment of a TCP, UDP, SCTP or ICMP packet.

OtherNotAFragment

A internet protocol (IP) version 4 or version 6 packet which is:-

• not TCP, UDP (and for Intel DPDK drivers, SCTP or ICMP);
• not a fragment

Other

Invalid or introduced after this code was written.
