Hi Alexender,
Thanks for the response. Please validate our understanding from the below

we have included the following in

rump_server again to load libdpdkif library.

But we are facing the unresolved symbols problem as follows.

failed to load -libraries, last error from "rumpnet_dpdkif":
/home/tcs/drv-netif-dpdk/rump/lib/librumpnet_dpdkif.so: undefined symbol:
rte_pktmbuf_init
To create dpdk intefaces using rump utilities, are we supposed load this
library (librumpnet_dpdkif) to rump_server ?? do we need some makefile changes
in my enviroment to overcome the above situation.
could you please help us in resolving the above problem.
Regards,
Manikanta.

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

rumpremote (unix://csock)$ ifconfig dpdk0 10.0.0.172 netmask 255.255.255.0

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.
