How could you let the bridge know netpoll is not sent to
the one that doesn't support netpoll during setup? This will
be complex, I am afraid.
Why does this matter at all?
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 told you in another mail that we should do away with
these callbacks and all the crazy 'npinfo' assignments
and just do it in the generic code.
I think ->ndo_poll_controller is not in the case that you talked about.
Thanks.
