Hi,
I have a bunch of tulip based network cards with 21143 chipset. These
Micronet made cards do not seem to work when connected to a 10 Mbit
hub (as I have in the lab setup) while running with a recent kernel:
Jul 10 11:41:52 orion kernel: Linux Tulip driver version 0.9.15-pre9 (Nov 6, 2001)
Jul 10 11:41:52 orion kernel: PCI: Found IRQ 5 for device 00:09.0
Jul 10 11:41:52 orion kernel: PCI: Sharing IRQ 5 with 00:04.2
Jul 10 11:41:52 orion kernel: tulip0: EEPROM default media type Autosense.
Jul 10 11:41:52 orion kernel: tulip0: Index #0 - Media 10baseT (#0) described by a 21142 Serial PHY (2) block.
Jul 10 11:41:52 orion kernel: tulip0: Index #1 - Media 10baseT-FDX (#4) described by a 21142 Serial PHY (2) block.
Jul 10 11:41:52 orion kernel: tulip0: Index #2 - Media 100baseTx (#3) described by a 21143 SYM PHY (4) block.
Jul 10 11:41:52 orion kernel: tulip0: Index #3 - Media 100baseTx-FDX (#5) described by a 21143 SYM PHY (4) block.
Jul 10 11:41:52 orion kernel: eth0: Digital DS21143 Tulip rev 65 at 0xb000, 00:C0:CA:30:CD:75, IRQ 5.
The hub shows a link beat after the module has been loaded, but the
link vanishes once the "ip link set dev eth0 up" was issued. No data
can be transferred.
|haber@orion[1/76]:~$ sudo mii-diag eth0
|Basic registers of MII PHY #32: 1000 784c 0000 0000 01e1 0000 0000 0000.
| Basic mode control register 0x1000: Auto-negotiation enabled.
| You have link beat, and everything is working OK.
| Your link partner does not do autonegotiation, and this transceiver type
| does not report the sensed link speed.
| End of basic transceiver informaion.
Please note that mii-diag claims link beat, which is not true.
|haber@orion[8/83]:~$ sudo mii-tool --force=10baseT-HD
|haber@orion[9/84]:~$ sudo mii-diag eth0
|Basic registers of MII PHY #32: 2000 7848 0000 0000 01e1 0000 0000 0000.

| Speed fixed at 100 mbps, half-duplex.
| Basic mode status register 0x7848 ... 7848.
| Link status: not established.
| Link partner information information is not exchanged when in fixed speed mode.
| End of basic transceiver informaion.
Please not that mii-diag report the speed that has just been forced to
10 mbps half-duplex as 100 mbps.
Using a 10/100 Mbit switch instead of the 10 Mbit hub solves this
problem.
|haber@orion[4/59]:~$ sudo mii-diag eth0
|Basic registers of MII PHY #32: 1000 784c 0000 0000 0041 45e1 0000 0000.

However, the switch clearly shows the 100 Mbit light "on", so I have
to - again - distrust mii-diag here, because the performance clearly
shows that we are not running 10 Mbit here (10 Mbyte in approx. 2 secs).
When I use an older kernel (2.2.18 from the Linuxcare BBC), the card
works on the hub:

Is this a known issue with the tulip driver in 2.4.18? Can I help with
debugging?

I have reported (and noticed ;) the same problem. I fixed the problem by
using older version of the tulip-driver (0.9.14 IIRC, available from the
sourceforge).
I don't know if this is fixed in the 2.4.19-pre's... hopefully so.
