Copy flags when cloning next_frames
The VLIB_FRAME_NO_FREE_AFTER_DISPATCH flag is not preserved when cloning next_frames, as a result VLIB_FRAME_FREE_AFTER_DISPATCH can erroneously be set for a frame (see vlib_get_next_frame_internal()) Change-Id: Ice1d7ddcb807e1168aa0c157d9474be492d102c2 Signed-off-by: Nikhil P Rao <nikhil.rao@intel.com>
