**
** Interface description for ethernet device driver
**
** $Log$
** Revision 1.5 2006/07/10 12:43:38 philip
** Safecopy support in ethernet drivers.
**
** Revision 1.4 2005/09/04 18:52:16 beng
** Giovanni's fixes to dpeth:
** Date: Sat, 03 Sep 2005 11:05:22 +0200
** Subject: Minix 3.0.8
**
** Revision 1.3 2005/08/03 11:53:34 jnherder
** Miscellaneous cleanups.
**
** Revision 1.2 2005/08/02 15:30:35 jnherder
** Various updates to support dynamically starting drivers.
** Output during initialization should be suppressed. Unless an error occurs.
** Note that main() can now be main(int argc, char **argv) and arguments can
** be passed when bringing up the driver.
**
** Revision 1.1 2005/06/29 10:16:46 beng
** Import of dpeth 3c501/3c509b/.. ethernet driver by
** Giovanni Falzoni <fgalzoni@inwind.it>.
**
** Revision 2.0 2005/06/26 16:16:46 lsodgf0
** Initial revision for Minix 3.0.6
