Thank you! I think this is super useful, and I agree FWIW that it
should be part of ethtool.  I suspect that it needs to be installed by
any package manager as part of ethtool install, into the right
directory.  Could be a followup patch?

And the only (minor) complaint I have about your patch is that the
commit message doesn't show how to install it (basically just copy
ethtool file from this patch to
f.e. /usr/share/bash-completion/completions/)

I did a quick touch test of it and it seemed to be completing ethtool
commands which made me really happy, especially the network interface
names which are so long.

And now I'm going to go and tell everyone I work with about this
patch. :-)
