Re-discoveries on Linux hosts which provide the {{lnx_if}} section may found new and vanished interfaces if the output of ethtool is missing. You have to perform a rediscovery on affected Linux hosts.
Moreover if you have already used a previous 1.6.0 version then some interface statistics may be faulty.
Details: lnx_if section consists of three parts: {{ip address}}, {{/proc/net/dev}} and {{ethtool}}. {{ip address}} and {{ethtool}} may be missing. If the index of {{ethtool}} is available we use this one. Otherwise we sort the output of {{/proc/net/dev}} as the agent does and calculate the index synthetically.
