A partner requested the ability to loop back TX onto an RX queue.
Expose perf/diagnostics counters. Query using XDP APIs and/or expose through Windows perf counter framework?

Found in https://dev.azure.com/mscodehub/WindowsXDP/_git/xdp/pullrequest/19220 Add support for querying NdisGetRssProcessorInformation from LWFs XdpGenericRssInitialize: // // RSS allows more processors than receive queues, but the RSS // implementation in TCPIP constrains the number...
When XDP transitions from independently managing RSS for each edge to letting upper layer components manage the miniport RSS (RemoveLowerEdgeRssSetting), XDP must perform 2 actions: 1) Plumb the upper edge...
