Hi Long/Stephen,
I was going through the hotplug handling code in netvsc PMD and need clarification.
Earlier with failsafe PMD , my dpdk app used to subscribe to hotplug events to set the checksum offloads to do software checksum calculation when VF was removed and switch to H/W checksum calculation when VF was added.
I see even with netvsc PMD , it does not do anything specific to RSS /checksum offloads in hotplug callbacks but initializes VF port (through ioctl) during hotplug add and removes VF port in hotplug remove callback. So my understanding is, the dpdk app should continue to handle the checksum offloads as part of hotplug callbacks and netvsc will not handle it automatically.
Can you confirm if this is correct?
Regards,
Nandini
