Hi Karl, I've build and tested your PR, but without the GCC7 patch, and
when I've tested it on el6, none of the guests had network access.
I had to revert the bridge changes to have them working
(CONFIG_BRIDGE_NETFILTER=m and CONFIG_BRIDGE=m).

Why did you want the BRIDGE built-in instead of a module?

Maybe you have something to setup the bridge (probably filter) properly,
or maybe something is different in the xen package between el6 and el7.
Any idea?

I still have to investigate the Xen pkg, and have a closer look at those
tests I'm running.

Thanks,
