From: Michal Privoznik <mprivozn@redhat.com>
In virnetlink.c there are two sections: the first one when
building WITH_LIBNL support, the other that provides stubs for
functions declared in the corresponding header file when building
without netlink support. But the stub implementation for
virNetlinkBridgeVlanFilterSet() was missing.

Based on the usage I thin this function needs to still set error to 0.
All callers for now do that before calling but still the documentation
states that non-zero code means a netlink error, which is not the case
here.

I wanted to complain that INTERNAL_ERROR is not appropriate; but it
seems that all the stubs in virnetlink.c have terrible errors.

No, this needs to be anything else but 'flags' otherwise our
sc_flags_usage syntax-check rule will complain. unusedflags perhaps?

Good point.

Indeed, I went with consistency over correctness.

Ah ... d'oh. I mentioned it just because some static analysis tool complained about argument names differing between definition and declaration; Anyways 'unusedflags' would likely be preferrable.
