Subject: [PATCH V2 08/20] tap: import linux multiqueue constants
Date: Fri, 25 Jan 2013 18:35:31 +0800	[thread overview]
Message-ID: <1359110143-42984-9-git-send-email-jasowang@redhat.com> (raw)
In-Reply-To: <1359110143-42984-1-git-send-email-jasowang@redhat.com>

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.
