So as long as I am working only in X I should ignore the logic in SharedIP and in my filtered 'in' routine use dlil_inject_if_input and in my filtered 'out' routine continue to use dlil_inject_if_output?

In my NKE I have attached some filtering using 'dlil_attach_interface_filter' and pointed my call back functions via this call.

The filtering works find and in my call back function, My_if_input(caddr_t cookie, struct ifnet **ifnet_ptr, struct mbuf **mbuf_ptr), I want to get/look at the filter ID of the calling filter. This is the value that was obtained in the previous calling to 'dlil_attach_interface_filter'.

Another question I have relating to the above statement, is that in My_if_input I am trapping the mbuf, Ethernet frame, as it is coming in. [snip]

Sorry for the delay; I haven't had time to look at this. Short answer: Yes :-} dlil_inject* injects into the indicated stream (input: World -> System; output: System -> World). The confusion arising from SharedIP (other than its twisted architecture) comes from the need to treat "World" on output as (World+X). Therefore, when Classic sends a frame to the "world", that includes X; the output processing then must (selectively) inject frames intended for X into the *input* stream (even though the frame is really going "out to the world").
