IPv4/IPv6 UDP punt node main loop.

This is the main loop inline function for IPv4/IPv6 UDP punt transition node.

Parameters

vm	vlib_main_t corresponding to the current thread
node	vlib_node_runtime_t
frame	vlib_frame_t whose contents should be dispatched
is_ipv4	indicates if called for IPv4 or IPv6 node

	)

IPv4 UDP punt node.

Node Identifier:: ip4-udp-punt

This is the IPv4 UDP punt transition node. It is registered as a next node for the "ip4-udp-lookup" handling UDP port(s) requested for punt. The buffer's current data pointer is adjusted to the original packet IPv4 header. All buffers are dispatched to "error-punt".

Parameters

vm	vlib_main_t corresponding to the current thread
node	vlib_node_runtime_t
frame	vlib_frame_t whose contents should be dispatched

Graph mechanics: next index usage

Sets:

vnet_buffer(b)->current_data
vnet_buffer(b)->current_len

Next Index:

Dispatches the packet to the "error-punt" node

IPv6 UDP punt node.

Node Identifier:: ip6-udp-punt

This is the IPv6 UDP punt transition node. It is registered as a next node for the "ip6-udp-lookup" handling UDP port(s) requested for punt. The buffer's current data pointer is adjusted to the original packet IPv6 header. All buffers are dispatched to "error-punt".
