Assume nobody runs current libvirt on kernels such as 2.6.26.
Kernel commit 9f9c9cbb60576a1518d0bf93fb8e499cffccf377 (released
in 3.8) mentions the new path and I believe it was added by:
commit 948af1f0bbc8526448e8cbe3f8d3bf211bdf5181
firmware: Basic dmi-sysfs support
(released in 2.6.39), but I cannot figure out how all that
kernel automagic works.

GLib implementation of g_dbus_connection_call_sync() calls
g_variant_ref_sink() on the passed @parameters to make sure they have
proper reference. If the original reference is floating the
g_dbus_connection_call_sync() consumes it, but if it's normal reference
it will just add another one.
Our mock functions were only freeing the @parameters which is incorrect
and doesn't reflect how the real implementation works.

Somehow this check was duplicated just below the original.
(I was at first skeptical that it's needed at all, since
GET_VLAN_VID_CMD was already present in kernel 2.6.32, but then I
realized that there is no higher level check for __linux__ around the
code that is conditional on WITH_DECL_GET_VLAN_VID_CMD; it only checks
for SIOCGIFVLAN and WITH_STRUCT_IFREQ - the latter is also present on
*BSD platforms, the former doesn't seem to be anywhere but Linux, but
I didn't want to change the effect of the conditional, so I left it in
(we could have also replaced WITH_DECL_GET_VLAN_VID_CMD, but possibly
there is a non-Linux platform that *does* have it...)

Lack of this one function (which is called for each active tap device
every time libvirtd is started) is the one thing preventing a
"WITHOUT_LIBNL" build of libvirt from being useful. With this
alternate implementation, guests using standard tap devices will work
properly even when libvirt is built without libnl support.

There was one stray bit of code in virnetdev.c that required libnl to
build, but wasn't qualified by defined(WITH_LIBNL). Adding that, plus
putting a similar check around a static function only used by that
aforementioned code, makes libvirt build properly without libnl3-devel
installed.
How useful it is in that state is a separate issue :-)

This flag was originally created to indicate that either 1) the build
platform wasn't linux, 2) the build platform was linux, but the kernel
was too old to have macvtap support. Since there was already a switch
there, the ability to also disable it when 3) the kernel supports
macvtap but the user doesn't want it, was added in. I don't think that
(3) was ever an intentional goal, just something that grew naturally
out of having the flag there in the first place (unless possibly the
original author wanted a way to quickly disable their new code in case
it caused regressions elsewhere).
Now that the check for (2) has been removed, WITH_MACVTAP is just
checking (1) and (3), but (3) is pointless (because the extra code in
libvirt itself is miniscule, and the only external library needed for
it is libnl, which is also required for other unrelated features (and
itself has no subordinate dependencies and takes up < 1MB on
disk)). We can therfore eliminate the WITH_MACVTAP flag, as it is
functionally equivalent to WITH_LIBNL (which implies __linux__).

macvtap support was added to the Linux kernel in 2.6.33. libvirt
checked for this by looking for MACVLAN_MODE_BRIDGE and IFLA_VF_MAX in
linux/if_link.h. This hasn't been necessary for a very long time, so
just gate on platform == 'linux' (and be sure to complain if someone
tries to enable it on a non-Linux platform).

it was missing. It's useful like was probably 6 months at most, but

WITH_VIRTUALPORT just checks that we are building on Linux and that
IFLA_PORT_MAX is defined in linux/if_link.h. Back when 802.11Qb[gh]
support was added, the IFLA_* stuff was new (introduced in kernel
2.6.35, backported to RHEL6 2.6.32 kernel at some point), and so this
extra check was necessary, because libvirt was being built on Linux
distros that didn't yet have IFLA_* (e.g. older RHEL6, all
RHEL5). It's been in the kernel for a *very* long time now, so all
supported versions of all Linux platforms libvirt builds on have it.
Note that the above paragraph implies that the conditional compilation
should be changed to #if defined(__linux__). However, the astute
reader will notice that the code in question is sending and receiving
netlink messages, so it really should be conditional on WITH_LIBNL
(which implies __linux__) instead, so that's what this patch does.

WITH_LIBNL will only be defined on Linux platforms (because libnl is a
library written to encapsulate parts of netlink, which is a Linux-only
API), so it's redundant to write:
#if defined(__linux__) && defined(WITH_LIBNL)
We can just check for WITH_LIBNL.

IFLA_VF_MAX was introduced to the Linux kernel in 2.6.35, and was even
backported to the RHEL*6* 2.6.32 kernel downstream, so it is present
in all supported versions of all Linux distros that libvirt builds
on. Additionally, it can't be conditionally compiled out of a
kernel. There is no reason to conditionalize any piece of code on
presence of IFLA_VF_MAX - if the platform is Linux, it is supported.
