VPPAPIGEN: Add union and enum support and IP4/IP6 address type.
Note: The Python, Java and C/C++ bindings must be updated before ip/ip_types.api can be used. ip_types.api: typedef ip4_address { u8 address[4]; }; typedef ip6_address { u8 address[16]; }; enum address_family { ADDRESS_IP4 = 0, ADDRESS_IP6, }; union address_union { vl_api_ip4_address_t ip4; vl_api_ip6_address_t ip6; }; typedef address { vl_api_address_family_t af; vl_api_address_union_t un; }; Change-Id: I22f67092f24db5bd650a03c6f446a84cd9fd1074 Signed-off-by: Ole Troan <ot@cisco.com>
