Greetings, I'm trying to add a Racal Interlan NI6510 to my Internet gateway in order to plug into it a cable from a Gandalf LANline 5242i ISDN adapter (T1 is outrageously expensive in Canada, but at least ISDN is OK). The NI6510 uses the Am79C960 chip, so I was hoping that the lnc driver would work, but I'm getting hang-ups as soon as I "ifconfig" the board. At boot time, the board gets seen as a "NE2100 with a Am79C90", so I guess that's not too healthy from the start (there is a comment in if_lnc.c that says the Am7990 and Am79C960 have different meanings for CSR3). The effect is that as soon as I type "ifconfig lnc0 198.168.73.172", the light flashes on the Gandalf box (which seems to indicate something happens on the LAN), the shell prompt comes back, but then the whole machine is frozen and only a hard reset will get it moving again. I assume that the registers on the NI6510 are different and that an interrupt is not being delivered correctly to the driver. Unfortunately, I don't have any NI6510 h/w documents handy. Is it hopeless, or can I easily get out of the hole? If it's too complicated, I'll just signal our support people to get them to purchase a cheapo NE2000 clone instead of spending tons of time fixing it.
