/*
 * IPv4 and IPv6 Fragmentation Nodes
 *
 * A packet sent to those nodes require the following
 * buffer attributes to be set:
 * ip_frag.header_offset :
 *     Where to find the IPv4 (or IPv6) header in the packet. Previous
 *     bytes are left untouched and copied in every fragment. The fragments
 *     are then appended. This option is used for fragmented packets
 *     that are encapsulated.
 * ip_frag.mtu :
 *     Maximum size of IP packets, header included, but ignoring
 *     the 'ip_frag.header_offset' copied bytes.
 * ip_frag.next_index :
 *     One of ip_frag_next_t, indicating to which exit node the fragments
 *     should be sent to.
