Build Update for david-marchand/ovs
-------------------------------------

Build: #12
Status: Canceled

Duration: 43 secs
Commit: ccbc32b (vhost_fixes)
Author: David Marchand
Message: netdev-dpdk: avoid reconfiguration on VIRTIO_NET_F_MQ changes

At the moment, a malicious guest might negotiate VIRTIO_NET_F_MQ and
!VIRTIO_NET_F_MQ in a loop which would be seen as qp_num going from 1 to
n and n to 1 continuously, triggering datapath reconfigurations at each
transition.

Limit this by only reconfiguring on increased qp_num.
The previous patch reduced the observed cost of polling disabled queues,
so the only cost is memory.
