Typedef Documentation

udp_encap_fixup_flags_t

typedef enum udp_encap_fixup_flags_t_ udp_encap_fixup_flags_t

UDP encapsulation.

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-plane

udp_encap_t

typedef struct udp_encap_t_ udp_encap_t

The UDP encap representation.

udp_encap_walk_cb_t

typedef walk_rc_t(* udp_encap_walk_cb_t) (index_t uei, void *ctx)

Callback function invoked when walking all encap objects.

Return non-zero to continue the walk.

UDP_ENCAP_FIXUP_UDP_SRC_PORT_ENTROPY	UDP source port contains an entropy/hash value for load-balancing by downstream peers.
