From 254941f323702dbebe3f9145fdb1ab24c5bd23c1 Mon Sep 17 00:00:00 2001 From: Willem de Bruijn Date: Tue, 13 Oct 2020 15:45:08 -0400 Subject: [PATCH] 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.
