Subject: [PATCH] virtio: enable indirect descriptors feature
|
|
|
|
Virtio indirect descriptors are supported by the data-path
|
|
but the feature bit is never set during feature negociation.
|
|
|
|
This patch simply adds VIRTIO_RING_F_INDIRECT_DESC back to
|
|
the supported features bit mask, hence enabling the use of
|
|
indirect descriptors when the feature is negociated with the
|
|
device.
