Detailed Description

Protocol type definitions and helper functions.

The protocol types are used with the GNRC communication interface, the Network interface API, the Network protocol registry, and the Packet to identify network protocols throughout the network stack.

To include a nettype into your build, use the corresponding pseudo-module e.g. to use GNRC_NETTYPE_IPV6 in your code, use

USEMODULE += gnrc_nettype_ipv6
