I use bonded interfaces to gain both performance and high availability.
They are bonded using the the standard ifenslave tool, and vblade is
given the bonded interface as an argument.

As we can see from the RX/TX stats, traffic isn't balanced 100%
between the interfaces,
and I'm not sure why that is. This setup works quite nicely for now, though.
