This series disables IOMMU feature by default, and introduce
a new flag passed at vhost device registration time to enable
it explicitly.
When disabled, patch 1 also disables reply-ack protocol feature
to avoid Qemu v2.7.0-v2.9.0 reply-ack bug with multiqueue.
Last patch adds a Vhost PMD "iommu-support" parameter to enable
the IOMMU feature.
Maxime Coquelin (3):
vhost: disable reply-ack protocol feature if iommu feature disabled
vhost: add flag to enable iommu support
net: vhost: add iommu-support parameter to enable IOMMU feature
