Hmmm maybe it's me, but something bugs me if a NIC driver is going to

blatant layering violation.... shouldn't the ifup/ifconfig scripts just
be fixed instead if this is critical behavior?

Maybe we should be faking this out from our hotplug scripts in the control VM, although triggering this from user space is probably a bit of a pain. Regardless, the function can be removed from the driver if it's too distasteful: it's only a performance 'hack' to get network traffic more quickly redirected when migrating a VM between physical hosts. Things won't break horribly if it's removed.
