[syslinux] [PATCH] pxe: fix OACK packet handling

[liu Aleaxander]

So, here is the new patch:

>From f7e36b4de4387f8662dbb88b550915a021e8f99b Mon Sep 17 00:00:00 2001
From: Liu Aleaxander <Aleaxander at gmail.com>
Date: Sat, 8 Aug 2009 16:05:08 +0800
Subject: [PATCH] core:PXELINUX: fix the OACK option parsing bug.

the current code can just handle one option beacuse I put the do-while loop
in the wrong position.
