1) Use the expected transmit count instead of the actual transmit count to determine when to stop a running packet generator when the user specifies a transmit limit.
2) Add a new packetio command line option, modules.packetio.dpdk.drop-tx-overruns. This option instructs the transmit path to drop packets instead of buffering them when the transmit queue is full.
This PR makes two main changes:
1) Use the expected transmit count instead of the actual transmit count to determine when to stop a running packet generator when the user specifies a transmit limit.
2) Add a new packetio command line option, modules.packetio.dpdk.drop-tx-overruns. This option instructs the transmit path to drop packets instead of buffering them when the transmit queue is full.
