Hello.

In the previous versions of python-ethtool there is a 9 chars limit for device name. In the newest version, we have a newline between device name and HW address so the limit is useless here.

I've created a simple patch. Github PR: https://github.com/fedora-python/python-ethtool/pull/31

Have a nice day.

This looks like a low-priority bug, but it's probably an easy fix engineering-wise.
python-ethtool is not on the ACL, so it probably won't get fixed in RHEL 7.5. Let me know if that's a problem.
