Did you change the option nic-offload= from its default "auto" to "yes" ?
With set to auto, it should not cause any failure.
Another issue could be that the ethtool code is too old and this error
should really just be a debug warning.
Regardless, if the connection works, and you are not expecting to be
using special nic's with hardware offload support, you can ignore
