dep8 tests are only hitting known flaky tests, so they are ok

Also the automated virt regression tests ran fine on all architectures.

Remaining: I'm waiting for the bug reporters to confirm test-ability and the MP review here

[Andreas Hasenack (ahasenack)]

+Subject: [PATCH 1/4] util: fixing wrong assumption that PF has to have netdev
+ assigned
+
+libvirt wrongly assumes that VF netdev has to have the
+netdev assigned to PF. There is no such requirement in SRIOV standard.
+This patch change the virNetDevSwitchdevFeature() function to deal
+with SRIOV devices which does not have netdev on PF. Also corrects
+one comment about PF netdev assumption.
+
+One example of such devices is ThunderX VNIC.
+By applying this change, VF device is used for virNetlinkCommand() as
+it is the only netdev assigned to VNIC.

+Subject: [PATCH 3/4] util: Fix for NULL dereference
+
+The device xml parser code does not set "model" while parsing the
+following XML:
+
+  <interface type='hostdev'>
+    <source>
+      <address type='pci' domain='0x0002' bus='0x01' slot='0x00' function='0x2'/>
+    </source>
+  </interface>
+
+The net->model can be NULL and therefore must be compared using
+STREQ_NULLABLE instead of plain STREQ.

+
+While in most cases the values are going to be much
+smaller than our arbitrary 4096 limit, there is really
+no guarantee that would be the case: in fact, a few
+aarch64 servers have been spotted in the wild with
+core_id as high as 6216.
+
+Take advantage of virBitmap's ability to automatically
+alter its size at runtime to accomodate such values.
