Subject: net/mac80211/debugfs: Convert to kstrou8_from_user

This patch replaces the code for getting an number from a
userspace buffer by a simple call to kstrou8_from_user.
This makes it easier to read and less error prone.

Since the old buffer was only 10 bytes long and the value is masked by a
nibble-mask anyway, we don't need to use kstrtoul but rather kstrtou8.

Kernel Version: v3.0-rc2

Subject: mac80211: Remove unnecessary OOM logging messages

Removing unnecessary messages saves code and text.

Site specific OOM messages are duplications of a generic MM
out of memory message and aren't really useful, so just
delete them.

Subject: mac80211: add flag to indicate HW only Tx-agg setup support

When this flag is set, Tx A-MPDU sessions will not be started by
mac80211. This flag is required for devices that support Tx A-MPDU setup
in hardware.

From 37a41b4affa33bb237d3692bf51f1b5ebcaf29d8 Mon Sep 17 00:00:00 2001

Subject: mac80211: add ieee80211_vif param to tsf functions

TSF can be kept per vif.
Add ieee80211_vif param to set/get/reset_tsf, and move
the debugfs entries to the per-vif directory.

Update all the drivers that implement these callbacks.
