Enum network_packet::HardwareOffloadLayer2PacketType

pub enum HardwareOffloadLayer2PacketType {
    Unknown,
    Ethernet(Option<HardwareOffloadCategorisedLayer2PacketType>),
    Other,
}

Hardware offload layer 2 packet type.

If the packet is a tunneled packet, then this is known as the Outer Layer 2 packet type.

Must DPDK drivers do not categorise and return Unknown, making this categorisation close to useless.

Variants

Unknown

Either:-

• Ignore this packet.
• HardwareOffload categorisation hasn't happened.

It seems possible that some DPDK drivers don't set RTE_PTYPE_L2_ETHER even on ethernet packets.

Ethernet(Option<HardwareOffloadCategorisedLayer2PacketType>)

Ether packet; may be further categorised.

Most drivers, excluding Intel's, do not categorise further.

Other

Invalid or introduced after this code was written.
