+Subject: [PATCH] qemu: Add virtio related options to vsock
+
+Add virtio related options iommu, ats and packed as driver element attributes
+to vsock devices. Ex:
+
+ <vsock model='virtio'>
+ <cid auto='no' address='3'/>
+ <driver iommu='on'/>
+ </vsock>

+(cherry picked from commit bd112c9e0f7523b90bf1362cf60deea7db05a32b)
+
+Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1941820
+
+Note: since the virtio option packed is not yet available in the code
+version it will also not be available with this backported patch.
