From eb9dce6c3eb5f980f5206427d4dd8d7aea0cf960 Mon Sep 17 00:00:00 2001 From: Pierre Pfister Date: Wed, 7 Sep 2016 10:46:18 +0800 Subject: [PATCH] net/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.
