net, neigh: introduce interval_probe_time_ms for periodic probe
commit ed6cd6a17896 ("net, neigh: Set lower cap for neigh_managed_work rearming") fixed a case when DELAY_PROBE_TIME is configured to 0, the processing of the system work queue hog CPU to 100%, and further more we should introduce a new option used by periodic probe Signed-off-by: Yuwei Wang <wangyuweihx@gmail.com> Signed-off-by: Paolo Abeni <pabeni@redhat.com>
