Hi Ilya,
thanks for testing this and reporting the problem. It appears
that the version that I posted ignores the initial database
configuration.
I think that the problem is solved by fixing one of the issues
pointed out by Mark in his review: in do_add_port(),
netdev_reconfigure() should be called before allocating and opening
the rxqs.
Thanks again for the feedback!
Daniele
