What do you mean by "send packets to the receive path"? Does that mean that a packet "sent" to the receive path is *not* transmitted on the network interface, but, instead, appears as if it were a packet that had arrived on that interface (and is processed by the Windows networking stack)?
Yes, this is exactly what I want.
If so, then...I know how to implement this in the driver layer. But I don't know howto add this interface to wpcap.dll. I don't want to change too much like adding a function call. What's the best practice to do this? Thanks. ...it is *completely unrelated* to anything libpcap/WinPcap currently does, and therefore *should* be done with a new function call.
I admit injecting packets into the receive path is a bit weird, but there's a guy asking for an adapter forwarding function, and I believe adding such a injecting means is a solution for him. Maybe there's a better way to do this job. I will forward his mail here. Cheers, Yang
