Struct ChecksumCapabilities 

#[non_exhaustive]
pub struct ChecksumCapabilities {
    pub ipv4: Checksum,
    pub udp: Checksum,
    pub tcp: Checksum,
    pub icmpv4: Checksum,
    pub icmpv6: Checksum,
}

A description of checksum behavior for every supported protocol.

This is what a device uses to tell the stack which checksums its hardware takes care of, so the stack doesn’t compute them again in software.

The default is Checksum::Both for every protocol: the stack computes and verifies everything itself.

A checksum the stack does not compute is written as zero, so that a device that fills it in finds a known value there.

The fields are the protocols with a checksum the stack handles. IGMP is not among them: its checksum is always computed and verified in software.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

ipv4: Checksum

Checksum behavior for the IPv4 header.

udp: Checksum

Checksum behavior for UDP.

tcp: Checksum

Checksum behavior for TCP.

icmpv4: Checksum

Checksum behavior for ICMPv4.

icmpv6: Checksum

Checksum behavior for ICMPv6.
