papi: vla list of fixed strings
Handle a variable length array of fixed strings. Like: fixed_string = VPPType("fixed_string", [["string", "data", 32]]) s = VPPType("string_vla", [["u32", "length"], ["fixed_string", "services", 0, "length"]]) Previously instead of packing and unpacking as strings, exception packed as u8 instead of list. Type: fix Signed-off-by: Ole Troan <ot@cisco.com> Change-Id: I501a8a4755828042e1539fd5a54eacec21c5e364 Signed-off-by: Ole Troan <ot@cisco.com>
