[dpdk-users] Running the quick start

[Sandeep Rayapudi]

Hi all,

I've installed DPDK on the machine that has Intel NICs. I followed the
steps from the Quick Start (
http://dpdk.org/doc/quick-starthttp://dpdk.org/doc/quick-start)
After making the NICs DPDK-COMPATIBLE, they are listed correctly.

Network devices using DPDK-compatible driver
============================================
0000:04:00.0 '82599ES 10-Gigabit SFI/SFP+ Network Connection' drv=igb_uio
unused=ixgbe
0000:04:00.1 '82599ES 10-Gigabit SFI/SFP+ Network Connection' drv=igb_uio
unused=ixgbe
0000:05:00.0 '82599ES 10-Gigabit SFI/SFP+ Network Connection' drv=igb_uio
unused=ixgbe
0000:05:00.1 '82599ES 10-Gigabit SFI/SFP+ Network Connection' drv=igb_uio
unused=ixgbe

Network devices using kernel driver
===================================
0000:02:00.0 'NetXtreme BCM5719 Gigabit Ethernet PCIe' if=eno1 drv=tg3
unused=igb_uio *Active*
0000:02:00.1 'NetXtreme BCM5719 Gigabit Ethernet PCIe' if=eno2 drv=tg3
unused=igb_uio
0000:02:00.2 'NetXtreme BCM5719 Gigabit Ethernet PCIe' if=eno3 drv=tg3
unused=igb_uio
0000:02:00.3 'NetXtreme BCM5719 Gigabit Ethernet PCIe' if=eno4 drv=tg3
unused=igb_uio

Other network devices
=====================
<none>

For DPDK-compatible NICs, the names of these interfaces is not shown, so
I'm unable to pass name of the NIC in iface parameter.

build/app/testpmd -c7 -n3 --vdev=eth_pcap0,iface=eth0
--vdev=eth_pcap1,iface=eth1 --
                  -i --nb-cores=2 --nb-ports=2 --total-num-mbufs=2048


If I pass the original name of the NIC before it is made a DPDK compatible,
it gives the error:
./build/app/testpmd -c7 -n3 --vdev=eth_pcap0,iface=eno49
--vdev=eth_pcap1,iface=eno50 -- -i --nb-cores=2 --nb-ports=2
--total-num-mbufs=2048

Any inputs on how to run this?

Thanks,
