The last_rx field in the loopback driver is updated on every xmit but is not used otherwise. Accesses to ->last_rx cause unecessary traffic on the interlink for NUMA systems which limits the performa

For one thing bonding load balancing uses it. You can argue that bonding of loopback devices is silly. But there are other things one might be able to do with last_rx and the fact that every driver f
These loopback driver SMP optimizations are starting to really driver me crazy. Correct or not, I suspect there are a non-trivial number of folks out there who use loopback performance as an indicato
