dummy interface for pfinet

[Marcus Brinkmann]

Hi,

as an exercise, I implemented a dummy interface for pfinet. Apply the
attached diff, and compile pfinet. The interface name is "dummy".

settrans /servers/socket/2 /hurd/pfinet -i dummy -a 192.168.0.1 -m 
255.255.255.0 -g 192.168.0.2

The dummy interface is the same as the dummy interface in linux:
A bottomless pit. You don't get a single packet out of it, and everything
you send to it is lost.

Note that the above local address 192.168.0.1 is recognized as local.
Stuff sent to this address is not lost, of course.

The implementation shows two areas where pfinet lacks:
Missing support for multiple interfaces, and no support for different types
of drivers (in my patch implemented as a switch on the device name).

Thanks,
Marcus
