nl-linux/generated/nl/linux/netdev.rb

Overview

Get device statistics, scoped to a device or a queue. These statistics extend (and partially duplicate) statistics available in struct rtnl_link_stats64. Value of the scope attribute determines how statistics are aggregated. When aggregated for the entire device the statistics represent the total number of events since last explicit reset of the device (i.e. not a reconfiguration like changing queue count). When reported per-queue, however, the statistics may not add up to the total number of events, will only be reported for currently active objects, and will likely report the number of events since last reconfiguration.
