Hi Stephen/Long, I did some more code instrumentation and I observed that when a hotplug add event is received, the conf is applied back to VF and offloads work as expected. I also observe that when VF is removed, the offloads still continue to work as expected. Is this because the offloads are not unset when VF is removed ? Regards, Nandini
