To be a bit more specific it would be good to have IF-MIB ifTable with the items from ifXTable as well: ifIndex ifMtu ifHighSpeed ifPromiscuousMode ifPhysAddress ifConnectorPresent ifHCInOctets ifHCInUcastPkts ifHCInMulticastPkts ifHCInBroadcastPkts ifInDiscards ifInErrors ifInUnknownProtos ifHCOutOctets ifHCOutUcastPkts ifHCOutMulticastPkts ifHCOutBroadcastPkts ifOutDiscards ifOutErrors A number of things are missing or weird in the DPDK stats interface. Then I get stuck trying to maintain them in my app instead and it's annoying. Also, it is nice to get the struct populated atomically so the values are as self-consistent as possible. If you have to call a function separately on each stat it makes them self-inconsistent because it is less atomically populated. >>From long experience, this inconsistency is quite annoying when trying to make very accurate traffic measurements in network management software.
