That is problematic. Existing apps depend on rtnetlink stats. But if we
don't count offloaded forwarded packets, the apps don't see anything.
Therefore I believe that this patchset approach is better. The existing
apps continue to work and future apps can use newly introduces sw_stats
to query slowpath traffic. Makes sense to me.
I agree with Jiri. It is a bad idea to depend on ethtool for any of
this stuff. Is there a way we can tag netlink stats instead
to indicate they are hardware or software?
Right, old API but the key here is that low level h/w stats are returned
by a different API.
By default ip, ifconfig, snmpd, etc all continue to get traditional S/W
stats - counters as seen by the CPU.
