[vortex] Does 3c59x.c support 3C905C-TXM ?

[Marcus Ramos]

Hi again,

Thank you very much for your reply.

First of all, I am sorry that I forgot an extra letter "C" in the question
below. My real concern was about the differences between 3C905C-TX and
3C905C-TXM (that is, the "M" suffix in the latter). Anyway, I am experiencing
the following problem, and if you or somebody else have comments on that I
will be very grateful.


SITUATION I:

Dell GX110 PIII running RH7 kernel 2.2.16. On-board NIC 3C905-TX.
/etc/modules.conf contains:
"alias eth0 3c59x".

The system boots OK and the interface works OK.

SITUATION II:

Same as above, except that an extra 3C905-TXM (not just -TX) is plugged into
a PCI slot. So now I have two NICs in theb box. A second line is added to
/etc/modules.conf, which then becomes:
"alias eth0 3c59x"
"alias eth1 3c59x"

The system boots OK but none of the interfaces work. When trying to use one
or the other, for example with ping, I get the message "Destination not
reachable". lsmod tells me that 3c59x is properly loaded and is being used by
2 interfaces (as I expected). But why isn't any of them working in this
situation ?

Regards,
Marcus.
