This an updated version of the patches. For reference, introduction of
the feature is here http://thread.gmane.org/gmane.linux.network/172941
Just tell me if you prefer I resend the full intro each time.

Compared to initial version, this v2 is

 - against net-next-2.6
 - fixed and more exhaustively build tested for various kernel
   configuration (w/ and w/o IPv6, IPv4, MIPv6, XFRM*, RO, ...).
   It adds some #ifdef but I did not found good ways to spare those.
 - built and tested on both current linux-2.6 and net-next-2.6 (*)

Comments welcome.

Try again, this time with ipv6 modular:

net/built-in.o: In function `xfrm_input_addr_check':
/home/davem/src/GIT/net-next-2.6/net/xfrm/xfrm_input.c:115: undefined reference to `xfrm6_input_addr_check'

You can't put xfrm6_input_addr_check into the ipv6.o object build if you want to
call it from the generic xfrm stack which is always built statically.

Put this and xfrm4_input_addr_check where it belongs, as an afinfo->op()
