This dmesg lines are suspicous to me:

10.

The MAC address is normally read from the EEPROM. But it's zero here which implies the read from SROM (aka EEPROM) failed. See this code in dmfe_init_one():
...
        /* read 64 word srom data */
        for (i = 0; i < 64; i++)
                ((__le16 *) db->srom)[i] =
                        cpu_to_le16(read_srom_word(db->ioaddr, i));

        /* Set Node address */
        for (i = 0; i < 6; i++)
                dev->dev_addr[i] = db->srom[20 + i];

        err = register_netdev (dev);
...

Given this driver only seems to use IO Port space (and not MMIO), I'll rule out write posting issues. Exception might be if SPARC port doesn't fully adhere to non-postable semantics of in/outw Port space ops.

Slightly more likely issue is endianess. Like PARISC, SPARC is big endian and the SROM is organized using 16-bit reads....but the data is zero'd, not byte swapped. I suggest you look for potential endian issues with control data. Note that outl/inl functions should be doing the endianess adjustment already (Big Endian CPU writing to a little endian bus device).

Lastly, I wonder if adding a udelay(5) after line 1583 and/or 1596 would help:

1582         outl(CR9_SROM_READ, cr9_ioaddr);
1583         outl(CR9_SROM_READ | CR9_SRCS, cr9_ioaddr);
1584 
1585         /* Send the Read Command 110b */
1586         SROM_CLK_WRITE(SROM_DATA_1, cr9_ioaddr);
1587         SROM_CLK_WRITE(SROM_DATA_1, cr9_ioaddr);
1588         SROM_CLK_WRITE(SROM_DATA_0, cr9_ioaddr);
1589 
1590         /* Send the offset */
1591         for (i = 5; i >= 0; i--) {
1592                 srom_data = (offset & (1 << i)) ? SROM_DATA_1 : SROM_DATA_0     ;
1593                 SROM_CLK_WRITE(srom_data, cr9_ioaddr);
1594         }
1595 
1596         outl(CR9_SROM_READ | CR9_SRCS, cr9_ioaddr);

Both outl's are essentially "back to back" with the next outl after each one. All other outl()'s in that routine have a udelay(5) between them.

I don't have any other brilliant ideas on what might be wrong.
Please try the above and/or other ideas you might have by "modprobe", check output, rmmod if necessary and repeat with a newly compiled module.

BTW, can you also post "lspci -vs 00:05.0" output?

I'd like the entire output but am specifically looking for the subsystem vendor/device output to see if maybe this card has weird byte ordering just for Sun/SPARC market.

here is the output

I try to use the udelay(5) after line 1583 and 1596 but the error
coming again after reboot.

Patch for linux-2.6.23 to add OpenFirmware support to drivers/net/tulip/dmfe.c

Patch for linux-2.6.23 to add OpenFirmware support to drivers/net/tulip/dmfe.c

Kövedi,
thanks for trying the regular tulip driver. I suppose that could be hacked to
support sparc64 as well but the phy support/initialization could get ugly. If
you can sort that out, I'd be happy to review the patches. If you can enable
more debugging/printk's, I'd also try to advise/help. This will be slow going
though and you'll need lots of patience.

If you might consider trying tulip again using IO port space instead of MMIO
space. If that works better, I'd wonder if tulip still has MMIO write posting
issues. I doubt it since tulip seems to work fine on ia64 and parisc - both
have significant PCI write posting behaviors. But try IO Port space anyway
(e.g. set TULIP_MMIO to N).

I didn't realize the dmfe driver _never_ worked for Sun Fire V100. It couldn't
have since it didn't have the required OpenFirmware support that tulip driver
has. I've added that to linux-2.6.23 patch (diff-2.6.23-dmfe_openfirmware-01)
and will attach that to this bug. I've not even compiled tested this since I
don't have a sparc64 x-build env setup. Please try it and let me know how it
goes.

I apply the patch and booting up the new kernel.
The patch is worked the devices are MAC addresses but the network is unworkable.
And I see in the the dmesg output, the Tx timeout - resetting to exist.

I try modprobe dmfe debug=1 but not print output.

Darn...but at least that fixes one problem. Thanks for testing the patch.

Can you try the dmfe driver from 2.6.21?
Probably want to apply the patch I proposed to 2.6.21.7 as well.

I'm wondering if this bug is related to http://bugzilla.kernel.org/show_bug.cgi?id=9094

which claims 2.6.21.7 works but 2.6.22.9 does not.

I apply the patch.

firewall linux-2.6.21.7 # patch -p1 < bugfix

Hunk #5 succeeded at 1589 (offset -32 lines).

and booting up with the 2.6.21.7 kernel. The devices not have MAC addresses but the error message diferent as 2.6.23.

I have a different architecture but I hope this could be of some help.

OS: Arch Linux.

When moving from Slackware to Arch, I started getting "eth0: Tx timeout - resetting" messages, every 2 seconds, rendering the network unusable.
Starting from a non-working configuration [1], I configured the kernel in order to get a set of settings [2], similar to those used for Slackware's kernel [3].

With the kernel resulting from settings at [2] the network became usable again and dmfe driver no longer prints that message so frequently, as seen in the kernel log.

-------------------------------

Here are the differences between the non-working .config and the working one. Unfortunately, there are some unrelated changes also. As they are also in the Sun config, my guess is the following changes are causing conflicts

it was just a bad BIOS :S buggy ACPI support.

Diego,
thanks for the additional info.
I don't know if this is exactly the same bug as originally reported.
The original bug report was for:
00:05.0 Ethernet controller: Davicom Semiconductor, Inc. 21x4x DEC-Tulip
compatible 10/100 Ethernet (rev 31)

Note the "rev 31" and and yours is reporting "rev 10".

Can you attach the full kernel log (dmesg output since boot) please?
(why I ask is explained below)

I also need to know which kernel version you are using. The kernel log should tell me that as well.

Was the .config file the only change? (ie built with the same tools and same source tree?)
Sounded like it but I want to be sure.

dmfe and tulip driver are not related AFAICT except they are in the same "tulip" subdirectory.

BUT, it's possible the tulip driver is being using instead of dmfe and it might work better for your particular card. dmesg output will confirm which driver was actually used.

DM9102 is the dmfe driver (just to avoid confusion).

I don't expect any of the other config changes would affect the dmfe driver.

thanks again for the report!

Ah OK!
thanks...you can ignore my requests for dmesg log then.

Original bug report:
http://bugs.gentoo.org/show_bug.cgi?id=196426

I tried Debian on a V100 too and here are my experiences. First, I had to supply "dmfe.blacklist=1" to kernel command line to get it to use tulip driver. This worked fine, the tulip driver in 2.6.22 package worked and I finished my install successfully. Then upgraded to latest unstable and 2.6.24-1 packages also worked fine with tulip.

Tried 2.6.25-rc7, with tulip and with dmfe (runtime unloaded tulip, loaded dmfe, got errors, unloaded dmfe and reloadid tulip to get my network back - so tulip could have initialized the hardware). Tulip worked, dmfe failed like described above (first no MAC and then Tx timeouts & reset).

Tested 2.6.25-rc8-00208-g7180c4c with the openfirmware patch and with phy patch from http://iou.parisc-linux.org/~grundler/diff/diff-2.6.23-rc3-dmfe_phy-01 both applied.
As expected, dmfe found the MAC address but it's still Tx timeouting:
dmfe: Davicom DM9xxx net driver, version 1.36.4 (2002-01-17)
eth0: Davicom DM9102 at pci0000:00:0c.0, 00:03:ba:11:b3:71, irq 9.
eth1: Davicom DM9102 at pci0000:00:05.0, 00:03:ba:11:b3:72, irq 10.
ADDRCONF(NETDEV_UP): eth0: link is not ready
eth0: Tx timeout - resetting
eth0: Tx timeout - resetting

IRQ-s and MAC addresses are the same as working tulip gets:
