    processing at 2HZ.  From Eric Dumazet.

+  3.3 Multiqueue tuntap interface:
+
+  From version 3.8, Linux supports multiqueue tuntap which can uses multiple
+  file descriptors (queues) to parallelize packets sending or receiving. The
+  device allocation is the same as before, and if user wants to create multiple
+  queues, TUNSETIFF with the same device name must be called many times with
+  IFF_MULTI_QUEUE flag.
+
+  char *dev should be the name of the device, queues is the number of queues to
+  be created, fds is used to store and return the file descriptors (queues)
+  created to the caller. Each file descriptor were served as the interface of a
+  queue which could be accessed by userspace.
+
+  #include <linux/if.h>
+  #include <linux/if_tun.h>
+
+  int tun_alloc_mq(char *dev, int queues, int *fds)

+      ifr.ifr_flags = IFF_TAP | IFF_NO_PI | IFF_MULTI_QUEUE;
+      strcpy(ifr.ifr_name, dev);

+  }
+
+  A new ioctl(TUNSETQUEUE) were introduced to enable or disable a queue. When
+  calling it with IFF_DETACH_QUEUE flag, the queue were disabled. And when
+  calling it with IFF_ATTACH_QUEUE flag, the queue were enabled. The queue were
+  enabled by default after it was created through TUNSETIFF.
+
+  fd is the file descriptor (queue) that we want to enable or disable, when
+  enable is true we enable it, otherwise we disable it
