[PATCH] Iptables multiport match fix

Hi,

The multiport match checks for the IPT_INV_PROTO flag in the 'flags'
member of struct ipt_ip instead of in the 'invflags' member.

(Where should I send this btw? The kernel part of iptables doesn't
seem to be in the netfilter CVS. Was I supposed to create a p-o-m
patch? Or send it directly to Marcelo?)
