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.
