Been waiting more than 4 years for a release with this.. Let's stop waiting and switch to the now 4 year old HEAD of the main branch. Many DSA switches will not produce useful statistics in the /proc/net/dev file used by default. It contains interfaces counters associated with the DSA slave ports, which counts traffic between the external ports and the CPU port. The usual expectation from snmp on a switch is that it returns the actual switched traffic per port. This is often exported using driver specific or phy specific ethtool counters. This update brings the ability to pull the per port snmp counters from configurable ethtool counters. Signed-off-by: Bjørn Mork <bjorn@mork.no>
