This file is only needed if mem_malloc uses the memp pools, which is not the 
case for the unix port. The win32 port can be set to that option, thus it needs 
the file.

The win32 port uses the pcap library (known from wireshark, for example), while 
the unix port uses some other mechanism to get on the wire (I think tapif or 
something). Indeed, pktif.c is ethernetif.c adapted to the pcap library, while 
pktdrv.c contains the actual code to interface the pcap library (used by 
pktif.c).

> test.c

This is the entry file (containing the main() function and some 
initialization). The unix port has a similar file (though named differently) 
which does about the same.

The unix port should already work like it is, you don't need to adapt anything, 
you only might have configure something to get it working. Unfortunately, I 
cannot help you there: I tried the unix port myself one time and found getting 
the network interface to work quite hard (compared to the windows port which 
kind of just works after installing pcap and configuring the MAC/IP addresses 
in the header file).

As I said above, this is the main entry file which the unix port also has 
(under a different name).
