Subject: [PATCH net-next 06/10] idpf: add rss_data field to RSS function parameters
From: Pavan Kumar Linga <pavan.kumar.linga@...el.com>
Retrieve rss_data field of vport just once and pass it to RSS related
functions instead of retrieving it in each function.
While at it, update s/rss/RSS in the RSS function doc comments.
