Unless there has been a volte face by the kernel developers, I was under
the impression that ToE functionality is not supported in any mainstream
Linux kernel. This suggests that ToE is not being used on your NIC.
If 'disabling' ToE by a jumper has an effect then that points to a bug in
the driver. Have you tried a recent driver/kernel ? Can you replicate the
problem with something like netperf ?
