Bug in ip_route_input_slow()

When doing load balancing over multiple interfaces on SUSE 10.0,
kernel-smp-2.6.13-15.10, i get the following messages:

I'm not sure of the meaning, but this message should be sent to netdev@vger.kernel.org. The bug has
most likely been fixed in kernels later than 2.6.13 (2.6.17.4 is the latest stable release), but the
tg3 experts on that list will know.

FWIW, this has been logged in Bugzilla:
https://bugzilla.novell.com/show_bug.cgi?id=190908
The SUSE 10.1 kernel doesn't exhibit this behaviour.
