netfilter: add IPv4/6 IPComp extension match support
With this plugin, user could specify IPComp tagged with certain
CPI that host not interested will be DROPped or any other action.
For example:
iptables -A INPUT -p 108 -m ipcomp --ipcompspi 0x87 -j DROP
ip6tables -A INPUT -p 108 -m ipcomp --ipcompspi 0x87 -j DROP
Then input IPComp packet with CPI equates 0x87 will not reach
upper layer anymore.
