Hi Manikanta,
You should be able to create and configure a DPDK port like any other
rumpkernel network interface. For example:
- using a DPDK-compatible ethernet interface already bound to igb_uio
- with a rumpkernel built with drv-netif-dpdk
- a rumprun-posix environment, configured to talk to my rumpkernel
… I can do the following:
rumpremote (unix://csock)$ ifconfig dpdk0
ifconfig: SIOCGIFFLAGS dpdk0: Device not configured
rumpremote (unix://csock)$ ifconfig dpdk0 create
rumpremote (unix://csock)$ ifconfig dpdk0
dpdk0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
address: a0:36:9f:ca:fe:be
rumpremote (unix://csock)$ ifconfig dpdk0 10.0.0.172 netmask 255.255.255.0
rumpremote (unix://csock)$ ping 10.0.0.1

In future, if you’re having issues running commands, please send both the
command and the output along with your emails. It will help us help you debug
your situation.
Thanks.
