* extends VPP's message definition language with the following syntax: u32 count: u8 array[count]; which is traslated to: u32 count; u8 array[0]; but now, python API representation generated by vppapigen contains information about where the array length is stored. * modifies existing response messages to use the new syntax Change-Id: I68210bc7a3a755d03d067e9b79a567f40e2d31f3 Signed-off-by: Marek Gradzki <mgradzki@cisco.com>
