HONEYCOMB-233: add support for mixing L2/L3 rules
In case of L2 interfaces, acls are translated into a chain of classify tables and assigned as L2 table. In case of L3 interfaces, acls are translated into ip4 and ip6 chains (eth only rules go to both chains, rest - depending on ip-version). Limitations: - it is not possible to define L3 rule without specifying ip-version (common header fields for IP4/IP6 have different offsets), - eth rules on L3 interfaces are applied only to IP traffic (vpp classfier limitation).
