[RFC,net-next,0/2] gve: Link IRQs, queues, and NAPI instances

Message

Greetings:

This RFC uses the netdev-genl API to link IRQs and queues to NAPI IDs so
that this information is queryable by user apps. This is particularly
useful for epoll-based busy polling apps which rely on having access to
the NAPI ID.

I've tested these commits on a GCP instance with a GVE NIC configured
and have included test output in the commit messages for each patch
showing how to query the information.

I hope to send this next week when net-next reopens as an official
submission, but wanted to send an RFC now in case there were any changes
requested from the GVE maintainers.

Thanks,
Joe
