[PATCH 0/1] Fix QEMU networking access to WAN

[Scott Garman]

Hello,

This fixes the IP masquerading settings so that networked QEMU sessions
can reach external networks.
    
It is a partial fix for [YOCTO #2329].

It's been tested on my Linux Mint 12 host as well as Saul's Fedora 16
and Ubuntu 11.04 hosts.
