Hello: This patch was applied to netdev/net-next.git (main) by David S.

Greetings: Welcome to v2. This was previously an RFC [1], see changelog below. I've only compile tested this series; I don't have the software for testing this so I am hoping some one from Microsoft can review and test this following the instructions below :) This change allows users to query the mapping of queues to NAPIs using the netdev-genl interface. Once this patch has been applied, this can be tested using the cli included in the kernel tree like this: $ ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/netdev.yaml \ --dump queue-get --json='{"ifindex": 2}' Substituting the ifindex above for the correct ifindex on your system (which is, presumably, a hyper-V VM). A sample of expected output would look like: [{'id': 0, 'ifindex': 2, 'napi-id': 145, 'type': 'rx'}, {'id': 0, 'ifindex': 2, 'napi-id': 145, 'type': 'tx'}] Which shows a mapping of queue ID (0) to NAPI ID (145) for both RX and TX queues. Having this mapping is extremely useful for user apps for a variety of use cases, including epoll-based busy poll which relies on the NAPI ID. It would be really great to add support for this API to hyper-V so that applications (including CI and automated testing facilities) could make use of this API in VMs. Sorry, I don't know much at all about hyper-V, but please let me know if there is anything I can do to help.
