[PATCH 4.11 18/78] mac80211: fix dropped counter in multiqueue RX

From: Greg Kroah-Hartman
Date: Mon Jun 19 2017 - 11:17:16 EST


4.11-stable review patch. If anyone has any objections, please let me know.

------------------

From: Johannes Berg <johannes.berg@xxxxxxxxx>

commit e165bc02a02c70e40d5c811c705ba269aeca0497 upstream.

In the commit enabling per-CPU station statistics, I inadvertedly
copy-pasted some code to update rx_packets and forgot to change it
to update rx_dropped_misc. Fix that.

This addresses https://bugzilla.kernel.org/show_bug.cgi?id=195953.
