TG3 doesn't work in kernel 2.4.27

TG3 doesn't work in kernel 2.4.27

[Tetsuo Handa]

Hello,

I'm using tg3.o with DHCP and PXE boot environment
and I updated from 2.4.26 to 2.4.27,
but tg3.o became not working with IBM BladeCenter.

I think tg3.o in 2.4.27 is generating something broken arp.
When I run 'arp' in the DHCP server (who doesn't use tg3.o),
the entry with <incomplete> status appears.
The IP address which has the <incomplete> status is
the DHCP client's (who is using tg3.o in 2.4.27).

The workaround I took is to replace tg3.h and tg3.c
in 2.4.27 with the files in 2.4.26, and it seems working fine.

Thanks.

David Miller is the tg3 maintainer, he will help you.

Does manual IP configuration work?

I compiled as a UP kernel but it wasn't the cause.
Also, I patched the above fix on 2.4.27-rc4 and
compiled as a UP kernel, but didn't work.

Now I would like to mail to Marcelo Tosatti, too.

Current Status:
 * The driver is tg3.o
 * The problem began with 2.4.27-rc4.
 * DHCP fails.
 * Static IP assignment shows no error, but network is still unreachable.
   ('ifconfig' and 'route add default gw' by hand)
 * DHCP packets are unreachable to DHCP server.
   (I don't know which options are used for tcpdump.
    I hear that 2.4.26 worked but 2.4.27 didn't. PXE's DHCP works. )
 * 'arp' at DHCP server shows a line with <incomplete> status.
 * Compiling as a UP kernel didn't solve the problem.
   (The box is Xeon 3.2 GHz / 1 CPU with hyper-threading)
 * Compiling as a UP kernel with the above fix didn't solve.
 * The error message "HW autoneg failed" appears.
   (But (I think) this message doesn't exist in tg3.c for 2.4.26,
    so I don't know autoneg were successful or not in 2.4.26,
    if helpful I will insert printk() and try.
    The link ups (if 2.4.26) 1000Mbps full duplex, off for TX and off for RX.)

Testsuo,

Please send the output of `lspci -vv`.  It might be helpful to know 
exactly which device is involved.

David,

FWIW, I think I'm seeing the same problem with the BCM5751 built-in to 
my HP xw4200...

This bug can only affect 5704 chips with fiber interfaces.

Just add this patch, it will fix the problem but it
is not the nicest fix.  I'll work on a better one.

It just disables the new Sun code, and uses the old
fiber handling for 5704.
