From 0bcad32b3870f9998fa1393418081cdda685272f Mon Sep 17 00:00:00 2001 From: Ole Troan Date: Tue, 11 Dec 2018 13:04:01 +0100 Subject: PAPI: Allow ipaddress object as argument and return values from API calls The API calls that use any of vl_api_address_t, vl_api_ip4_address, vl_api_ip6_address_t, vl_api_prefix_t, vl_api_ip4_prefix_t, vl_api_ip6_prefix_t now accepts either the old style dictionary, a text string (2001:db8::/32) or an ipaddress ojbect. Unless it is called with '_no_type_conversion':True, it will also return an appropriate ipaddress object.
