A robust solution would rely on the kernel driver to reclaim the resources during a VF reset. Nevertheless, this fix is not harmful and provides temporary relief for the issue until a proper solution can be implemented in the kernel driver. Acked-by: Qi Zhang <[email protected]> Applied to dpdk-next-net-intel. Thanks Qi
