Thanks for the patch.
I think that netdev_max_flows should be an atomic_uint32_t because it is
accessed from multiple threads.
Usually the replies to appctl commands are very terse, so that a
successful reply to change a value would just be empty and the reply for
getting a value would just be the raw value, and usually we don't
include a new-line at the end.
Thanks,
Ben.
