[PATCH net-next 0/3] virtio_net: Link queues to NAPIs

[Joe Damato <jdamato@fastly.com>]

Greetings:

Recently [1], Jakub mentioned that there were a few drivers that are not
yet mapping queues to NAPIs.

While I don't have any of the other hardware mentioned, I do happen to
have a virtio_net laying around ;)

I've attempted to link queues to NAPIs, taking care to hold RTNL when it
seemed that the path was not already holding it.

Note: It seems virtio_net uses TX-only NAPIs which do not have NAPI IDs.
As such, I've left the TX NAPIs unset (as opposed to setting them to 0).

See the commit message of patch 3 for example out to see what I mean.

Thanks,
Joe
