linuxppc vs. LinkSys, v0.91

[Brian Warner]

Hi all.

I'm having a problem with a LinkSys 10/100 card that I picked up at Fry's
cheap ($25). It connects fine to a cheap 10baseT hub when in my x86 linux box
(stock 2.2.6 kernel, tulip driver), but I can't get it to send packets on my
powerpc linux box. Here's the data:

 linux-2.2.8 with tulip.c v0.91 copied into place, built as a module
 LinkSys "EtherFast" 10/100 card, the kind with the PNIC from what I can tell
 10baseT hub, nothing fancy.

As far as I can tell, the card is detected properly, the MAC address comes out
correctly (no endian issues there). The link light comes on, the 10baseT hub's
link light comes on. But no packets go out, and I see "Transmitter Stopped"
messages in the logs.

A transcript is appended. (The goofiness with 10.0.0.0/8 addresses versus
11.0.0.0/8 comes from already having a 10net link on a different card, and
needing to make the packets go out the right interface. Pay no attention to
the subnet behind that curtain. I had the same problems with a different, more
valid set of local addresses before.)

The outgoing arp triggered by the ping attempt never makes it to the wire.
ifconfig reports a handful of TX errors, about one per arp attempt. If I try
to ping into the interface from another host, the arps never resolve but the
broadcasts appear to get counted in the "RX dropped" slot.

I seem to have the same problem regardless of whether I leave the
autonegotiation alone or if I force it to 9 (MII 10baseT), 11 (MII
autoselect), or 12 (10baseT), which were the only values that made sense to
me.

I haven't been able to compile the tulip-diag.c program, it seems to use some
isa-bus specific functions that aren't available under linuxppc. I'm still
looking into it, might just be a problem with getting the right includes. (I
know how handy that kind of program can be.. I had to write a 21143 driver for
an embedded system at work and used something similar all the time).

Some comments on the powerpc list suggested trying the de4x5 driver with
similar cards, but it completely failed to recognize the card. Seems like it
really insists upon 2114[0123] and nothing else. But with the recent powerpc
changes that went into tulip.c v0.91, I'm hopeful that my problem is something
minor. v0.91 is a far cry better than the version that came with linux-2.2.8:
that one hung the entire machine as soon as the interface was brought up. This
version has a much more well-behaved bug. :)

Any ideas? Any other tests I could run to help track this one down?

thanks,
 -Brian
