Dear all,

I download dpdk 1.8.0 and build drv-netif-dpdk repository successful. But
when i use librumpnet_dpdkif, there is error like this:
root@juno:~/rump-kernel/drv-netif-dpdk#./rump/bin/rump_server
-lrumpnet_dpdkif unix:///tmp/rumpctrlsock
failed to load -libraries, last error from "rumpnet_dpdkif":
/root/rump-kernel/drv-netif-dpdk/rump/lib/librumpnet_dpdkif.so: undefined
symbol: rte_pktmbuf_init

The failed reason is that the librumpnet_dpdkif.so does not include the
dpdk mbuf library, can you tell me how to use librumpnet_dpdkif.so in the
application?

Is there [official rumpkernel.org] documentation somewhere saying that you should use dpdk with rump kernels like that? If yes, can you tell where so I can fix it?

In any case, look into the "examples" directory for examples on application use -- a fairly limited selection of examples, but examples nonetheless.
