[net-next v2 0/2] gve: Link IRQs, queues, and NAPI instances

Posted by Joe Damato 1 month, 4 weeks ago

Greetings:

Welcome to v2. The previous revision was an RFC [1].

This series 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.

Thanks,
Joe
