The i40e driver rejects the most general HWTSTAMP filter

Because of disabling L4 timestamping (UDP) in the security fix for Intel Ethernet Controller X710 and XL710 family described in the INTEL-SA-00063 advisory, the i40e device driver rejects the most general HWTSTAMP filter. This problem only affects the Intel X710 devices, not the newer X722 device. (BZ#1431964)
