Looks like this bug fell through the cracks.

It's still valid, and easy to reproduce in a VM:

$ multipass launch daily:xenial -n x1
$ multipass exec x1 cat /sys/class/net/ens3/speed
-1

And if you have munin-node installed:
$ multipass exec x1 sudo munin-run if_ens3 config|tail -n 3
up.max -1000000
up.info Traffic of the ens3 interface. Maximum speed is -1 Mb/s.
down.max -1000000

With the fix, it asks you to install ethtool or another such tool:
up.info Traffic of the ens3 interface. Unable to determine interface speed. Please install ethtool, wireless-tools, mii-tool or whatever is appropriate for the interface.

But that also reports unknown speed, probably because it's a vm virtio device. But the speed can be set manually:

sudo ethtool -s ens3 speed 1000 duplex full

In any case, I guess unknown speed is better then a negative one, right?
