Hi,
        I am unable turn off  rx and tx checksum on VMware ESX 3.0 service
console (based on RHEL 3) and Arch Linux (now Ark) with ethtool.

On ESX
=======

#ethtool -K vmnic0 tx off rx off
Cannot set device rx csum settings: Function not implemented
(vmnic0 is a broadcom nic here)

On Arch Linux .8
===============

#ethtool -K eth0 tx off rx off
Cannot set device rx csum settings: Operation not supported.
(eth0 is an AMD PCnet32 nic )

Could somebody explain me why am I getting this? Would it be because the
NICs don't support it?  Any other way to achieve this?
