Hi,
I’m trying to use dpdk with Mellanox ConnectX-3 Pro NIC.
I built PMD for it according to instructions on
"http://dpdk.org/doc/guides/nics/mlx4.html http://dpdk.org/doc/guides/nics/mlx4.html " and tried to launch
testpmd app but got following error:
[tim@centos]$ sudo ./testpmd -c 0x03 -n 2 -w 0000:b3:00.0 – --rxq=2 --txq=2 -i
EAL: Detected 36 lcore(s)

Done

What can be the reason of testpmd does not start correctly?
