Two mistakes here: - Automatic assignment of Rx queues to PMD threads has always existed - it was simply switched from round-robin allocation to utilization-based allocation - The above, along with the 'pmd-rxq-rebalance' command, was added in OVS 2.9.0 - not OVS 2.8.0 - while the 'pmd-rxq-show' command was added in OVS 2.6.0 and modified in OVS 2.9.0
Correct both of these and modify the NEWS entry for this to clarify things a little (it took a bit of git spelunking and bothering people on IRC to figure out).
