After commit 8d8fc29d02a33e4bd5f4fa47823c1fd386346093
(netpoll: disable netpoll when enslave a device), it is
no longer possible to use netconsole together with bridged
KVM guests.

I can see why the change looked reasonable from a networking
point of view, but this has completely disabled netconsole
functionality for a common KVM use case.

After the change, netconsole refuses to bind to eth0.

Since the bridge interface does not support polling,
netconsole cannot use that, either.


Bridge does support polling now. :) You can just setup
netconsole on a bridge device.

Thanks.
