Re: Problem with extended-match deletion

Ok Sumit,
now perhaps I've found my error:
I define:

static struct iptables_match bwcontrol = {
         NULL,
         "bwcontrol",
         NETFILTER_VERSION,
         IPT_ALIGN(sizeof(struct ipt_bwctrl_info)),
-->>>>  IPT_ALIGN(sizeof(struct ipt_bwctrl_info)),
         &help_bwcontrol,
         &init_bwcontrol,
         &parse_bwcontrol,
         &final_check,
         &print_bwcontrol,
         &save_bwcontrol,
         opts
};

Thank you very much!!!
