Check whether overriding of priority per VLAN works - don't know yet how, possibly
Verify that frames with different priorities are queued properly - probably need to define
using HP detection
many STREAMS with traffic of different priorities between the same ports of Spirent tester.
Need to set EP apprpriately
It might be that Spirent has such tests.
