This patch adds two functions, netif_reset_xps_queue and netif_set_xps_queue. The main idea behind these two functions is to provide a mechanism through which drivers can update their defaults in regards to XPS. Currently no such mechanism exists and as a result we cannot use XPS for things such as ATR which would require a basic configuration to start in which the Tx queues are mapped to CPUs via a 1:1 mapping. With this change I am making it possible for drivers such as ixgbe to be able to use the XPS feature by controlling the default configuration.
