[dpdk-users] Unable to launch testpmd with Mellanox ConnectX-3 Pro NIC

[Timur Bogdanov]

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" and tried to launch
testpmd app but got following error:

[tim at centos]$ sudo ./testpmd -c 0x03 -n 2 -w 0000:b3:00.0 -- --rxq=2 --txq=2 -i

EAL: Detected 36 lcore(s)

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