Please use only 2 ports with 1RX queue and 1 TX queue each to get l3fwd run=
ning. Try with these 2 below.
0000:02:00.0 'Ethernet Controller XL710 for 40GbE QSFP+ 1583' drv=3Digb_uio=
 unused=3Dvfio-pci
0000:02:00.1 'Ethernet Controller XL710 for 40GbE QSFP+ 1583' drv=3Digb_uio=
 unused=3Dvfio-pci

You can use more ports/queues but then you'll have to change the -config op=
tion depending on how many cores do you want to use.

The cmd that I've provided in my previous post is specifically for 2 ports =
with 1RX and TX queue each and 2 cores.

I suggest that you restart your machine, if possible, to unbind all ports f=
rom igb_uio and start from scratch.
Otherwise use the dpdk-seup.py script to do the clean-up.
