Still not working, dpdk interface is still down.

One error (/etc/freerouter/errors.log) I noticed:

java.net.BindException: Permission denied (Bind failed) at java.net.PlainSocketImpl.socketBind:PlainSocketImpl.java:-2/java.net.AbstractPlainSocketImpl.bind:AbstractPlainSocketImpl.java:452/java.net.ServerSocket.bind:ServerSocket.java:395/java.net.ServerSocket.bind:ServerSocket.java:349/prtLocTcp.<init>:prtLocTc

I think this had to do with the line tcp2vrf 23 host 23.

So I changed it to tcp2vrf 2324 host 23. and the error stopped

I want to start with basic step of just one DPDK interface (0000:00:06.0), is the hw-config below ok:

hwid emu

If freerouter is not able to use/detect dpdk interface, does it log the error somewhere?
