lcp_xc_inline()

		vlib_node_runtime_t *	node,
		vlib_frame_t *	frame,
		ip_address_family_t	af
	)

X-connect all packets from the HOST to the PHY.

This runs in either the IP4 or IP6 path. The MAC rewrite on the received packet from the host is used as a key to find the adjacency used on the phy. This allows this code to start the feature arc on that adjacency. Consequently, all packet sent from the host are also subject to output features, which is symmetric w.r.t. to input features.

X-connect all packets from the HOST to the PHY on L3 interfaces.

There's only one adjacency that can be used on thises links.
