From 4e4f9ae7da90b55fe77307e58c867aa6b02a7384 Mon Sep 17 00:00:00 2001 From: Jason Wang Date: Wed, 30 Jan 2013 19:12:29 +0800 Subject: tap: import linux multiqueue constants Import multiqueue constants from if_tun.h from 3.8-rc3. A new ifr flag IFF_MULTI_QUEUE were introduced to create a multiqueue backend by calling TUNSETIFF with the this flag and with the same interface name many times. A new ioctl TUNSETQUEUE were introduced. When doing this ioctl with IFF_DETACH_QUEUE, the queue were disabled in the linux kernel. When doing this ioctl with IFF_ATTACH_QUEUE, the queue were enabled in the linux kernel.
