Make testpmd txd/rxd/txq/rxq configurable in guest
- Add option to configure vring qsz for testpmd when running in guest [make 256 as default] - Add option to configure number of queues for testpmd when running in guest [make 1 as default] Change-Id: I4ecd24ba4a24d6d212b10cd6d24f5b016fb63fd9 Signed-off-by: pmikus <pmikus@cisco.com>
