I applied the patch to dpdk_merge here

The variable 'cnt' is initialized and reused in multiple function calls
inside netdev_dpdk_send__() and is confusing sometimes. Instead introduce
'batch_cnt' to hold the original packet count and 'tx_cnt' to store
the final packet count resulting after filtering and qos operations.
Finally 'tx_cnt' packets gets transmitted on the respective 'qid'.
