Transmit packet metadata.

Fields

id: TxId

The transmit ID.

segment_count: usize

The number of segments to follow.

len: usize

The total length of the packet in bytes.

offload_ip_header_checksum: bool

Offload IPv4 header checksum calculation.

l3_protocol, l2_len, and l3_len must be set.

offload_tcp_checksum: bool

Offload the TCP checksum calculation.

l3_protocol, l2_len, and l3_len must be set.

offload_udp_checksum: bool

Offload the UDP checksum calculation.

l3_protocol, l2_len, and l3_len must be set.

offload_tcp_segmentation: bool

Offload the TCP segmentation, allowing packets to be larger than the MTU.

l3_protocol, l2_len, l3_len, l4_len, and tcp_segment_size must be set.

l3_protocol: L3Protocol

The L3 protocol, needed when performing any of the offloads.

l2_len: u8

The length of the Ethernet frame header.

l3_len: u16

The length of the IP header.

l4_len: u8

The length of the TCP header.

max_tcp_segment_size: u16

The maximum TCP segment size, used for segmentation.
