2017-12-16	PAPI: Add docstrings to unit tests.	Ole Troan	1	-0/+17
	Change-Id: I0e20100c9e2ca4e951f605a79d48c04ff47864cb Signed-off-by: Ole Troan <ot@cisco.com>
2017-10-31	VPP PAPI: Error in unserializer for non-array compound types.	Ole Troan	1	-0/+438
	A bug in the decoder of messages when there was a non-array compound type. The typical result was an error message from the struct library: "error:unpack_from requires a buffer of at least 4 bytes" Change-Id: Ie30fec6fc39b9f4177b54fa4adc4fc69674f0e12 Signed-off-by: Ole Troan <ot@cisco.com>
2017-10-25	VPP-1033: Python API support arbitrary sized input parameters.	Ole Troan	1	-0/+31
	Dynamically calculate the required buffer size to pack into based on message definition. Also add input parameter length checking. Change-Id: I7633bec596e4833bb328fbf63a65b866c7985de5 Signed-off-by: Ole Troan <ot@cisco.com>
