The packet driver interface that I shipped off to Clarkson was very basic: it grabs all incoming packets rather than filtering on packet types. Modifying it to do static filtering (i.e. all ARP, RARP, IP) is pretty trivial. (This is what's needed for coexistence with NetWare or other non-IP stacks.) Modifying it for dynamic filtering based on individual UDP or TCP ports, etc. is _much_ harder, and in general not particularly useful: how, for example, do you persuade NCSA Telnet to use a TCP port which doesn't clash with one used by a PC-NFS Toolkit app?
