feature: provide a u16 version of vnet_feature_next
Type: improvement when using vlib_buffer_enqueue_to_next the 'nexts' parameter is an array of u16, but vnet_feautre_next takes a u32. this is a simple wrapper to address the impedence mismatch. Signed-off-by: Neale Ranns <nranns@cisco.com> Change-Id: I0fa86629e979e313344eb68442dc35a7b9537a8f
