[NETFILTER]: Add u32 match
Along comes... xt_u32, a revamped ipt_u32 from POM-NG,
Plus:
* 2007-06-02: added ipv6 support
* 2007-06-05: uses kmalloc for the big buffer
* 2007-06-05: added inversion
* 2007-06-20: use skb_copy_bits() and get rid of the big buffer
and lock (suggested by Pablo Neira Ayuso)
