Subject: [net-next rfc 3/3] tuntap: increase the max queues to 16
Date: Wed, 19 Jun 2013 13:40:52 +0800 [thread overview]
Message-ID: <1371620452-49349-4-git-send-email-jasowang@redhat.com> (raw)
In-Reply-To: <1371620452-49349-1-git-send-email-jasowang@redhat.com>
Since we've reduce the size of tun_struct and use flex array to allocate netdev
queues, it's safe for us to increase the limit of queues in tuntap.
