Hi,
Is it possible to configure dpdk-pktgen so that it will start only
transmitting packets, without Rx mode ?
I could not find a way to achieve it.
More specifically, I mean starting dpdk-pktgen so that it won't call
rte_eth_rx_burst() ?
(rte_eth_rx_burst() is called from pktgen_main_receive(), which is in
turn invoked from pktgen_main_rxtx_loop() and from
pktgen_main_rx_loop() in app/pktgen.c ?
Regards,
KW

No, at this time pktgen-dpdk will always attempt to do RX calls as some PMDs like bonding need that RX call for timing.
