Hi,
This chip appears on some Cabletron 22xx cards (that I happen to have and have
been asked to use). These chips do not show the usual signature. Offset 14
is 0x0 and offset 15 is 0x0 too. I have, for the sake of it, checked offset
13 and it is 0x0 too, nothing very promising to use for detecting specific cards.
I have tweaked the 2.2.2 kernel just enough to get it recognized. It seems to
give a chip id of 2261 (nothing surprising since plain 79C961 is 2260). I can
read the isapnp-set IRQ and DMA channel, I can read the Ethernet address that
starts with 00 00 1d (that I have been told is common with Cabletron), I can
ifconfig it and I have used it to sniff in promiscuous mode on a live network.
I have not gone any further yet.
Any information on this?
I have also seen a couple of very strange things in the lance code. While
init_module refuses to do autoprobing and insists in being given an io=0xNNN
parameter, it goes ahead ignoring it happily and using just its preconfigured
list of io addresses to probe.
The second problem may be caused by hacking with my toes, but the module does
not unload cleanly. It remains in (deleted) state and rmmod and lsmod make
the kernel barf, pushing the kernel to unstability until forcibly rebooted.
Any hint?
Thanks in advance,
Julio
