Typedef Documentation

UDP encapsualtion.

A representation of the encapsulation of packets in UDP-over-IP. This is encapsulation only, there is no tunnel interface, hence it is uni-directional. For decap register a handler with the UDP port dispatcher. Fixup behaviour. Actions performed on the encap in the data-plance

typedef struct udp_encap_t_ udp_encap_t
