This looks good, but I have to ask you to merge those two modules into
one single xt_ipcomp, they are fairly small and we can save the
overhead of having two different modules. Moreover, at quick glance I
don't see any dependency with IPv4/IPv6 exported symbols that may
cause ifdef pollution.

Please, see net/netfilter/xt_tcpudp.c as reference to rework this.
Thanks.
