You have been subscribed to a public bug: The unsigned vf->num_mac in Ubuntu18.04.1 LTS i40e driver 2.1.14-k will be decreased to below zero when VF is trying to delete the MAC address which is added by PF and then add a new MAC address. And after this issue happens, VF won't be able to send/receive packets, and excepting for broadcast address, mac_filter_hash is empty in dumped VSI info.
