Because currently we check netpoll support by ->ndo_poll_controller,
for example, tap driver doesn't have ->ndo_poll_controller now,
if I choose the target "@192.168.0.2/br0" where "192.168.0.2" is owned
by "tap0" which is managed by "br0", netconsole may not work.

I think ->ndo_poll_controller is not in the case that you talked about.

Thanks.
