[Fwd: Kernel 2.4 problem with 3C905B NIC]

Hello,
I am currently having problems with the 3c59x driver and I was told that
someone at this address (Bogdan?) could help.
Following instructions from Documentation/networking/vortex.txt, I have
generated the relevant diagnostics. I have also forwarded the original
e-mail I sent onto the kernel mailing list (right at the end).
It would appear that the 3c59x driver is unable to auto-negotiate with
this card/hub combination (see "*** Link Jabber! ***" below). For
reference, the D-Link hub to which the NIC is attached is model DFE-808.
As mentioned, I have tried to set options to force the card into various
modes, but it has not worked.
I have the 3c90x driver working but I would like to see the 3c59x driver
working because it comes in the standard Linux kernel distribution. I'm
not the only one with this configuration. So the main aim of this e-mail
is to debug and help fix this problem. Let me know if more info is
required. Thanks,
Ed-T.

Subject: Kernel 2.4 problem with 3C905B NIC
Date: 03 Jul 2003 19:24:36 +0100
I am currently using kernels 2.4.21-rc1 and 2.4.22-pre2.
I think there is a problem with the 3c59x module. Between two machines
lies a D-Link 100Base-TX Fast Ethernet Hub and a Netgear DS104 switch. I
think the D-Link has only half-duplex capability.
NICs at both ends initialise in 100Mbit mode.
What happens is that during large transfers, there are a very large
number of collisions on the network. This results in the transfer rate
slowing down to somewhere between 3KB-7KB per second.
Googling shows that there have been a number of problems in the past
regarding Linux and the 3C905B. History indicates that card appears to
work on Windows machines but have serious performance problems under
Linux in certain circumstances.
I have tried the various duplex module options and nothing helps. In
fact long transfers appear to trigger a Tulip lockup at the other end.
For those suffering, I have found a temporary work-around. Build the
driver (3c90x-102.tar.gz) at:
http://support.3com.com/infodeli/tools/nic/linuxdownload.htm
Despite all the compilation warnings, all works well! Transfer speeds
have increased to between 7MB-9MB per second, which is what I would
expect it to be.
The 3com site says that the driver is unsupported. Pity. Is there a
maintainer for the 3c59x module? The last entry in 3c59x.c was by akpm
July 2001. I presume this issues has been around for a while.
Ed-T.
