[libvirt] [libvirt-tck] [RFC] 802.1Qbg test scripts



Hi Daniel,
I am currently looking into TCK test cases to verify setting 802.1Qbg
functionality from libvirt. My current approach requires changes to some
library functions in lib/Sys/Virt/TCK/.
I would appreciate your feedback about these changes before continuing
much further.
I also attach the test case.

Thanks in advance.
