Greetings: This is an RFC to get feedback before submitting an actual series and because I have a question for igc maintainers, see below.
This series addss support for netdev-genl to igc so that userland apps can query IRQ, queue, and NAPI instance relationships. This is useful because developers who have igc NICs (for example, in their Intel NUCs) who are working on epoll-based busy polling apps and using SO_INCOMING_NAPI_ID, need access to this API to map NAPI IDs back to queues. See the commit messages of each patch for example output I got on my igc hardware. My question for maintainers: In patch 2, the linking should be avoided for XDP queues. Is there a way to test that somehow in the driver? I looked around a bit, but didn't notice anything. Sorry if I'm missing something obvious.
