Subject: [Intel-wired-lan] [PATCH iwl-next 1/5] idpf: add virtchnl functions to
manage selected queues

From: Michal Kubiak <redacted>

Implement VC functions dedicated to enabling, disabling and configuring not
all but only selected queues.

Also, refactor the existing implementation to make the code more modular.
Introduce new generic functions for sending VC messages consisting of
chunks, in order to isolate the sending algorithm and its implementation for
specific VC messages.

Finally, rewrite the function for mapping queues to q_vectors using the new
modular approach to avoid copying the code that implements the VC
message sending algorithm.
