From 93f0490e5deb9445737cabf0e436f3288a4042b7 Mon Sep 17 00:00:00 2001 From: Tamizh chelvam Date: Wed, 7 Oct 2015 10:40:04 +0530 Subject: Revert "mac80211: remove exposing 'mfp' to drivers" This reverts commit 5c48f1201744233d4f235c7dd916d5196ed20716. Some device drivers (ath10k) offload part of aggregation including AddBA/DelBA negotiations to firmware. In such scenario, the PMF configuration of the station needs to be provided to driver to enable encryption of AddBA/DelBA action frames.

Change the only driver using it (rt2x00) to simply use the DTIM period instead of the "max sleep" time.

Move the value to ifmgd, advertise it only in managed mode, and remove it from ethtool as it's available through better interfaces.
