/* The buffers returned by these functions are all allocated with a

 * However, take into account that when the packet dissection
 * completes, these buffers will be automatically reclaimed/freed.
 * If you need the buffer to remain for a longer scope than packet lifetime
 * you must copy the content to an wmem_file_scope() buffer.
