   Fixed i40e issue that occurred when a DPDK application didn't initialize

+* **i40e: Fixed maximum of 64 queues per port.**
+
+  Fixed the issue in i40e of cannot supporting more than 64 queues per port,
+  though hardware actually supports that. The real number of queues may vary,
+  as long as the total number of queues used in PF, VFs, VMDq and FD does not
