From 5fd0b838efac16046509f7fb100455d0463b9687 Mon Sep 17 00:00:00 2001 From: Petr Machata Date: Wed, 2 Mar 2022 18:31:23 +0200 Subject: net: rtnetlink: Add UAPI toggle for IFLA_OFFLOAD_XSTATS_L3_STATS The offloaded HW stats are designed to allow per-netdevice enablement and disablement. Add an attribute, IFLA_STATS_SET_OFFLOAD_XSTATS_L3_STATS, which should be carried by the RTM_SETSTATS message, and expresses a desire to toggle L3 offload xstats on or off. As part of the above, add an exported function rtnl_offload_xstats_notify() that drivers can use when they have installed or deinstalled the counters backing the HW stats. At this point, it is possible to enable, disable and query L3 offload xstats on netdevices. (However there is no driver actually implementing these.)
