io-net send

I have trouble with send messages over my own driver: protocol and
converter layers are implemented. description:

if i have one Ethernet driver send operation works fine,
but only when I plug into test PC another Ethernet device I
got a trouble: there no messages send into network,
but all functions reports that all is all right.

can You give me some counsel?
