ethernet-parser: deal with unsupported ethtool selftest
It is valid for the Linux ethernet driver to not support selftest; handle
that situation correctly by introducing an UNSUPPORTED
result type and an
OK
quality level.
We have other options:
- We could simply re-use the
POOR
quality level and not addOK
if preferred. - Or we could also simply consider it as an ethtool
FAIL
and not addUNSUPPORTED
if preferred.
Please let me know if you agree to consider this case of ethtool selftest unsupported + ping ok as a pass, and if you prefer another option.
Thanks!
