EOF error when loading plugin on Cumulus Linux

[wmclendon]

Attempting to use snapd ethtool plugin on Cumulus Linux to pull interface statistics. Loading plugin generates following error:

vagrant@leaf01a:~/snap/plugins$ snapctl plugin load snap-plugin-collector-ethtool
Error loading plugin:
unexpected EOF

Attached is log from snapd console
snap_ethtool_error.txt

Cumulus Linux is a linux-based network operating system for whitebox switches, and I think a tool like this running would be very useful. Unfortunately it appears Cumulus Linux ships with a pretty old version of ethtool:

vagrant@leaf01a:~$ ethtool --version
ethtool version 3.4.2

unfortunately it doesn't look like a newer version of ethtool is in their repo at this point in time.

This is an interesting use case. I guess the output of ethtool -S and ethtool -i would be helpful to compare. I'm guessing due to version the output is somewhat different than other versions of Linux.
