Previously the check lnx_if used the output of the ethtool command to determine if an interface is up or down. There was a fallback in case ethtool was not available, or did not report valid data at all (happens on broken interfaces). However, these fallback could not detect interfaces which break during runtime.
The linux agent now reports additional information collected with the ip link command. In case the ethtool information is missing the lnx_if check will now use the data from ip link instead.
