Hi, When I running latest vpp in master, I found the CPU cycle cost by "error-drop" node had increased. The reason is in vlib_buffer_free_inline with CLIB_HAVE_VEC128, sum will always be 1, and buffers will be free one by one. For fixing the issue, I have submitted a patch https://gerrit.fd.io/r/17600.
