It is possible to check if PF set a MAC address or not through the hw->mac.addr variable. hw->mac.addr set by i40e_vf_parse_hw_config(), call stack is: In PF side i40e_pf_host_process_cmd_get_vf_resources() eth_addr_copy(vf->mac_addr, vf_res->vsi_res[0].default_mac_address) In VF sise i40evf_init_vf() i40evf_get_vf_resources() i40e_vf_parse_hw_config() memcpy(hw->mac.addr, vsi_res->default_mac_addr) Updated code is after i40evf_get_vf_resources() and can benefit from hw->mac.addr variable.
