[yellowfin] GNIC-II problem on SuSE 7.3 2.4.16 kernel

[Chris Worley]

I'm resurrecting an old Hamachi card that should work, but I wouldn't be
surprised if the card was at fault.

The Hamachi module that came w/ SuSE's rev of the 2.4.16 kernel loads
fine, Transmits fine, but doesn't receive.  The RX error count
increments swiftly, with a few packets received (although, not enough to
see one valid ping).  The switch sees packets being both sent and
received and logs no errors.

So, I downloaded Don's latest driver (v1.04 11/17/2002), the driver in
the kernel was version: 1.01+LK1.0.1 5/18/2001.  The 1.01+LK1.0.1
version had the notes: "fix lack of pci_dev<->dev association" and
"ethtool support (jgarzik)".

I compiled the newer driver with the incantation being used by the
kernel's "make" rather than the one suggested at the bottom of the
source file:

    gcc -D__KERNEL__ -I/usr/src/linux-2.4.16.SuSE/include -Wall -Wstrict-prototypes -Wno-trigraphs -O2 -fomit-frame-pointer -fno-strict-aliasing -fno-common -pipe -mpreferred-stack-boundary=2 -march=i686 -malign-functions=4  -DMODULE   -c -o hamachi.o hamachi.c

... and likewise for pci-scan (with warnings):

    gcc -D__KERNEL__ -I/usr/src/linux-2.4.16.SuSE/include -Wall  -Wstrict-prototypes -Wno-trigraphs -O2 -fomit-frame-pointer -fno-strict-aliasing -fno-common -pipe -mpreferred-stack-boundary=2 -march=i686 -malign-functions=4  -DMODULE   -c -o pci-scan.o pci-scan.c
    In file included from pci-scan.c:60:
    /usr/src/linux-2.4.16.SuSE/include/linux/module.h:20: warning: `_set_ver' redefined
    /usr/src/linux-2.4.16.SuSE/include/linux/modsetver.h:9: warning: this is the location of the previous definition
    
If I use the compile command line suggested at the end of the source
files, the "version.h" #include squeals about not using the proper file.

Loading this driver, I get the oops:

Does that provide enough clues for someone to give a suggestion on how
to proceed?

Thanks,
