In linux kernel since version 2.6.12  
This is a network (Ethernet) device which attaches to your parallel
port. Read Documentation/networking/DLINK.txt as well as the
Ethernet-HOWTO, available from
<http://www.tldp.org/docs.html#howto>, if you want to use
this. It is possible to have several devices share a single parallel
port and it is safe to compile the corresponding drivers into the
kernel.

To compile this driver as a module, choose M here: the module
will be called de620.
