I don't believe this is a bug in Checkbox, checkbox can only use the
info that the kernel and system tools provide. This could be a driver
issue, or perhaps a cabling issue. Could you
A: verify the cables are plugged into the correct places and check via ethtool
what the connect speeds are for each port.
B: swap the cables on the SUT, and re-check ethtool output to see if port 0
STILL shows 1Gbit, or see if the 1Gb speed follows the cable.
C: Redo step A but on the 4.15 kernel rather than 4.18, to see if this is a
regression of some sort.
D: Happy Fun Bonus: Try 16.04 GA to see if this is present on 4.4 as well
(maybe not necessary, but worth looking into for due diligence).
I also added the kernel in case this is something we need to look at
from a driver perspective.
Here is lshw for that machine that shows the kernel thinks that the port
is 1Gbit:
