/** \brief FIB path
    @param sw_if_index - index of the interface
    @param weight - The weight, for UCMP
    @param preference - The preference of the path. lowest preference
    is prefered
    @param is_local - local if non-zero, else remote
    @param is_drop - Drop the packet
    @param is_unreach - Drop the packet and rate limit send ICMP unreachable
    @param is_prohibit - Drop the packet and rate limit send ICMP prohibited
    @param is_udp_encap - The path describes a UDP-o-IP encapsulation.
    @param is_dvr - Does the route resolve via a DVR interface.
    @param is_source_lookup - The the path is a deaggregate path (i.e. a lookup
    	   		      in another table) is the lookup on the packet's
			      source address or destination.
    @param afi - dpo_proto_t protocol that describes the next-hop address
    @param via_label - The next-hop is a resolved via a local label
    @param next_hop[16] - the next hop address
    @param next_hop_id - Used when the path resolves via an object
                         that has a unique identifier. e.g. the UDP
                         encap object
