In the series above, any fields which were previously a part of TestPmdRxqInfo
dataclass, and were not needed for our current testsuites, were dropped when we
shifted to a rxqinfo base class and 2 child classes for txq and rxq
respectively. 

I can see why this was done, but it is worth discussing at an upcoming meeting
whether we should continue with this practice in other cases, or attempt to
provide complete structures for testpmd output, even before they're needed for
a testsuite. In my view it is simpler to just support all fields possible in
the given dataclass instead of add them in piecemeal as testsuites are added.

For context, the original dataclass, which represents all the values returned
from "show rxq info <port_id> <queue_id>":
