Thanks for looking at our code.

You are right, this is why Sara made this commit:

commit 854d773e4ab5869200004af4ca5d851730849903
Author: Sara Sharon <sara.sharon@xxxxxxxxx>

    iwlwifi: mvm: improve RSS configuration
    
    Improve current RSS configuration:
     * Use netdev_rss_key instead of keeping a local copy.
     * Configure also UDP hashing to have UDP traffic spread across queues.
     * Do not direct RSS traffic to our fallback queue.
