[PATCH] psd option parsing

[Phil Oester <kernel@linuxace.com>]

[-- Attachment #1: Type: text/plain, Size: 311 bytes --]

psd match is too greedy with options, and doesn't play well with
other matches.  For example:

	# iptables -A INPUT -m psd -m recent --set -j DROP
	iptables v1.2.11: missing optarg
	Try `iptables -h' or 'iptables --help' for more information.

Below patch makes it less greedy.

This fixes bugzilla #18
