CONFIG_NET_UDP_MISSING_CHECKSUM

Accept missing checksum (IPv4 only)

Type: bool

Help

RFC 768 states the possibility to have a missing checksum, for debugging purposes for instance. That feature is however valid only for IPv4 and on reception only, since Zephyr will always compute the UDP checksum in transmission path.

Direct dependencies

NET_UDP && NET_IPV4 && !NET_RAW_MODE && NETWORKING

(Includes any dependencies from ifs and menus.)

Defaults

No defaults. Implicitly defaults to n.
