I would appreciate any help someone might be able to provide on my
issue. I did try the following based on reading some forum posts and bug
reports:
ethtool -K eth2 tx off
However, I still get errors similar
to the below with the above command activated. It doesn''t appear to
have
made any difference.

Additionally, I was able to configure the NIC through
