docs: networking: update XPS to account for netif_set_xps_queue
With the introduction of netif_set_xps_queue, XPS can be enabled by the driver at initialization. Update the documentation to reflect this, as otherwise users may incorrectly believe that the feature is off by default. Fixes: 537c00de1c9b ("net: Add functions netif_reset_xps_queue and netif_set_xps_queue") Signed-off-by: Willem de Bruijn <willemb@google.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
