Just passing the result of "inet_pton(AF_INET, '90.1.2.1') should work. u8 address[16] in python doesn't take a Python list, but a byte string. Let me add that to the documentation too. ;-) Cheers, Ole > > Best Regards > Yulong Pei > > -----Original Message----- > From: vpp-dev@lists.fd.io [mailto:vpp-dev@lists.fd.io] On Behalf Of Ole Troan > Sent: Wednesday, May 8, 2019 4:45 PM > To: Pei, Yulong <yulong....@intel.com> > Cc: vpp-dev@lists.fd.io; csit-...@lists.fd.io; Ni, Hongjun > <hongjun...@intel.com>; Liu, Yu Y <yu.y....@intel.com>; Kinsella, Ray > <ray.kinse...@intel.com> > Subject: Re: [vpp-dev] [csit-dev] how to know data type mapping between > *.api.json with PYTHON API ? > > Hi again, > >> Thanks for you kindly help.
