 * Moved from linux/include/freeswan/ipsec_ipip.h,v

 * Revision 1.1  2003/12/13 19:10:16  mcr
 * 	refactored rcv and xmit code - same as FS 2.05.
 *
 * Revision 1.1  2003/12/11 20:14:58  mcr
 * 	refactored the xmit code, to move all encapsulation
 * 	code into protocol functions. Note that all functions
 * 	are essentially done by a single function, which is probably
 * 	wrong.
 * 	the rcv_functions structures are renamed xform_functions.
