/*

 * =s ip
 * strips outermost IP header
 * =d
 *
 * Strips the outermost IP header from IP packets, based on the IP Header
 * annotation.
 *
 * Note that the packet's annotations are not changed.  Thus, the packet's IP
 * header annotation continues to point at the IP header, even though the IP
 * header's data is now out of range.  To correctly handle an IP-in-IP packet,
 * you will probably need to follow StripIPHeader with a CheckIPHeader or
 * MarkIPHeader element, thus marking the packet's inner header.
