[dpdk-dev] [PATCH v2] examples/flow_filtering: add Tx queues setup process

[Wei Zhao <wei.zhao1@intel.com>]

This example do not has the process of set up tx queues, but
some NIC start up process will be blocked if this is no tx queue
and only rx queues. So add tx queues setup process in main code.

Signed-off-by: Wei Zhao <wei.zhao1@intel.com>

v2:
-add support the new tx offloads.
