Not on purpose.

We have a management port (eth0) on the system, and that is the one that should be used
for inter-hostapd communication.  We want to be able to support routed mode as well
as bridged mode with hostapd, and either way, it will not be using eth0 for any data traffic.

Any idea how to configure this, and/or if we need external patches to make this work?
