From d656a4c6ead6c3f252b2f2532bc9735598f7e317 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 10 Jun 2021 22:08:16 +0200 Subject: mac80211: consider per-CPU statistics if present If we have been keeping per-CPU statistics, consider them regardless of USES_RSS, because we may not actually fill those, for example in non-fast-RX cases when the connection is not compatible with fast-RX. If we didn't fill them, the additional data will be zero and not affect anything, and if we did fill them then it's more correct to consider them. This fixes an issue in mesh mode where some statistics are not updated due to USES_RSS being set, but fast-RX isn't used.
