From 77c96404a4cf16ffa0720a3fbf45839cc16018ac Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Fri, 12 Jun 2015 14:40:45 +0200 Subject: mac80211: remove key TX/RX counter This counter is inherently racy (since it can be incremented by RX as well as by concurrent TX) and only available in debugfs. Instead of fixing it to be per-CPU or similar, remove it for now. If needed it should be added without races and with proper nl80211, perhaps even addressing the threshold reporting TODO item that's been there since the code was originally added.
