There was an example how to use it in the pach (last patch in series). Say we have remote system with eth0 set up and running. So we may sign in into this system remotely. If we have to confugure bridge on such a system (that even eth0 has to be the bridge port) we connect to this system via eth0 then add bridge br0 and run it via ifconfig br0 up, turn on via_phys_dev feature and evetually add eth0 as a bridge port. We will have small delay in session until port get forwarding state but after we could continue work remotely on the system without reconfiguring routing table. Even ssh session being used during configuration will continue operate. So except a delay no session interrupt. I hope, need a good testing ;) > On Mon, May 11, 2009 at 5:46 AM, Cyrill Gorcunov <gorcunov@xxxxxxxxxx> > wrote: >> Hi, >> >> here is RFC for new via_phys_dev bridge feature. >> In short -- it allows to use some bridge port as >> bridge itself with already configured routing table. >> >> More details with example you may found in patches. >> >> Please review.
