util: virnetdevtap: stats: fix txdrop on FreeBSD
That commit was correct about this no longer being required for FreeBSD,
but missed that the code is also built on macOS.
Rather than testing for this field in meson though, we can simply use
a platform conditional test in the code.

[PATCH] tests: add FreeBSD dependencies
by Roman Bogorodskiy
Add some FreeBSD-specific libraries (-lutil, -lkvm) to tests dependencies.
Without that, FreeBSD 11.x, which uses the GNU ld, fails to link tests.
Interestingly, newer FreeBSD versions that use LLVM ld tolerate this
behaviour and builds successfully as is.

[libvirt PATCH v2 0/3] Add support for vDPA network devices
by Jonathon Jongsma
vDPA network devices allow high-performance networking in a virtual
machine by providing a wire-speed data path. These devices require a
vendor-specific host driver but the data path follows the virtio
specification.
The support for vDPA devices was recently added to qemu. This allows
libvirt to support these devices. It requires that the device is
configured on the host with the appropriate vendor-specific driver.
This will create a chardev on the host at e.g. /dev/vhost-vdpa-0. That
chardev path can then be used to define a new interface with
type='vdpa'.
Changes in v2:
- split patches
- add qemu capability
- disallow migration for vdpa devices

[PATCH] qemu_namespace: Be tolerant to non-existent files when populating /dev
by Michal Privoznik
In 6.7.0 release I've changed how domain namespace is built and
populated. Previously it used to be done from a pre-exec hook
(ran in the forked off child, just before dropping all privileges
and exec()-ing QEMU), which not only meant we had to have two
different code paths for creating a node in domain's namespace
(one for this pre-exec hook, the other for hotplug ran from the
daemon), it also proved problematic because it was leaking FDs
into QEMU process. To mitigate this problem, we've not only
ditched libdevmapper from the NS population process, I've also
dropped the pre-exec code and let the NS be populated from the
daemon (using the hotplug code). But, I was not careful when
doing so, because the pre-exec code was tolerant to files that
doesn't exist, while this new code isn't. For instance, the very
first thing that is done when the new NS is created is it's
populated with @defaultDeviceACL which contain files like
/dev/null, /dev/zero, /dev/random and /dev/kvm (and others).
While the rest will probably exist every time, /dev/kvm might not
and thus the new code I wrote has to be tolerant to that.
Of course, users can override the @defaultDeviceACL (by setting
cgroup_device_acl in qemu.conf) and remove /dev/kvm (which is
acceptable workaround), but we definitely want libvirt to work
out of the box even on hosts without KVM.
