I once had a card that uses the MX98713 and tried to work on NetBSD
by modifying if_de.c, but I wasn't able to resolve
the 'abnormal interrupt' problem. I don't have the card now.
The MX98713 chip has already been supported by FreeBSD and
ported to OpenBSD. This driver is if_mx.c. To work the chip
correctly, I recommend porting if_mx.c to NetBSD than modifying
See http://www.freebsd.org/~wpaul/Macronix and OpenBSD source archive.
Datasheets of MX98713 (in PDF) could be obtained from www.macronix.com,
but I cannot connect the server now....???
But I have them, if you need them, I'll send you. Please mail me.
