I am still facing an issue with the mount version.
Mounting the driver works fine and the interface is visible with ifconfig.
As soon as I try to associate an IP-Address with the device, ifconfig hangs and does not return.
It also seems as if the other active ethernet connections are disconnected, as I can't connect to the target through 
qconn anymore.
I have tracked down the issue to the init function of the driver and this instruction:

ifp->if_flags_tx |= IFF_RUNNING;

I took this instruction from the speedo implementation. I assume it enables transmission?
When I remove this, mount works and I can assign an IP-address just fine, but I can't transmit any data.
When using a second io-pkt-v4 instance I don't face this issue.

Any ideas?

Clemens
