[Bug 785668] Re: bonding inside a bridge does not update ARP correctly when bridged net accessed from within a VM

[Serge Hallyn]

Natty is still affected.

Since qemu isn't needed to show the bug, you can now trivially test this
inside a natty kvm container by giving it two NICs, setting up
/etc/network interfaces as shown above, and using lxc as follows:

   apt-get install lxc debootstrap
   mkdir /cgroup
   mount -t cgroup cgroup /cgroup
   cat > /etc/lxc.conf << EOF
   lxc.network.type=veth
   lxc.network.link=br0
   lxc.network.flags=up
   EOF
   lxc-create -t natty -n lxc -f /etc/lxc.conf
   lxc-start -n lxc

When not using balance-rr, the container's network is fine.  When using
balance-rr, it can't get a dhcp address.

Next step is probably to look at the hwaddr handling in the kernel
source, and talk to upstream.
