mpls: add mpls_interface_dump
Add an API call mpls_interface_dump() which returns a list of mpls_interface_details: - If no sw_if_index is given, all MPLS enabled sw_if_index are returned. - If a particular sw_if_index is given, and it doesn't exist, an empty list is returned. - If a sw_if_index exists and has MPLS enabled, a list of that one sw_if_index is returned. Tested: - Create 3 loopback interfaces - Call for ~0 and for sw_if_index 0..5 all return empty lists - set int mpls loop0 enable - set int mpls loop1 enable - Call for ~0 returns 2, and the call for sw_if_index=1 and =2 (the loopbacks) returns each a list of one sw_if_index 1 resp 2, the other values of sw_if_index return empty list - set int mpls loop0 disable - Call for ~0 returns 1, and the call for sw_if_index=2 (loop1) returns both a list of one sw_if_index=2, the other values of sw_if_index return empty list - set int mpls loop1 disable - Call for ~0 and for sw_if_index 0..5 all return empty lists Example Python3 API program: ``` api_response = vpp.api.mpls_interface_dump() print(f"Response is {api_response}") for i in [ 0, 1, 2, 3, 4, 5 ]: api_response = vpp.api.mpls_interface_dump(sw_if_index=i) print(f"Response[{i}] = {api_response}") ``` Type: improvement Change-Id: If87f7d7f8972d99260e859757dbcb251c6fa54a8 Signed-off-by: Pim van Pelt <pim@ipng.nl>
