Hi Dpdk Team,
I am new to dpdk and am trying to run dpdk pktgen application by command
mentioned below :
./pktgen -c 0x1f -n 3 --vdev=eth_pcap0,iface=enp2s0 -- -P -m "[1:3].0"
Before run the application i execute the script named "dpdk-devbind.py
--status" It's showing status as mentioned below:
Network devices using DPDK-compatible driver
============================================
<none>
Network devices using kernel driver
===================================
0000:02:00.0 'RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller'
if=enp2s0 drv=r8169 unused= *Active*
0000:04:01.0 '82546EB Gigabit Ethernet Controller (Copper)' if=enp4s1f0
drv=e1000 unused=
0000:04:01.1 '82546EB Gigabit Ethernet Controller (Copper)' if=enp4s1f1
drv=e1000 unused=
Other network devices
=====================
<none>
It is showing no interface are under the DPDK-compatible driver list, Is it
means that we are not using the interface enp2s0 with dpdk?
if not, Is it affecting on performance of pktgen application ?
And Next I to bring the interfaces "enp2s0" from kernel driver list to the
"DPDK-compatible driver" list as shown below

0000:02:00.0 'RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller'

drv=e1000 unused=igb_uio,uio_pci_generic

=====================
<none>
but I am not able to got the it interface name and not in active mode also,
How to use now pktgen application without interface name?
Thanks in advance for quick solution
