PAPI: Add support for format/unformat functions.
With the introduction of new types, like vl_api_address_t it is now possible to call a message using one of those functions with a string representation. E.g. for an IP address ip_add_address(address="1.1.1.1/24") The language wrapper will automatically convert the string into the vl_api_address_t representation. Currently the caller must do the reverse conversion from the returned named tuple with the unformat function. rv = get_address_on_interface(sw_if_index=1) print(VPPFormat.unformat(rv.address)) Change-Id: Ic872b4560b2f4836255bd5260289bfa38c75bc5d Signed-off-by: Ole Troan <ot@cisco.com>
