| 4 | Subject: [PATCH] virtio: enable indirect descriptors feature |
| 5 | |
| 6 | Virtio indirect descriptors are supported by the data-path |
| 7 | but the feature bit is never set during feature negociation. |
| 8 | |
| 9 | This patch simply adds VIRTIO_RING_F_INDIRECT_DESC back to |
| 10 | the supported features bit mask, hence enabling the use of |
| 11 | indirect descriptors when the feature is negociated with the |
| 12 | device. |
