ca9938fea5 [PATCH] mac80211: fix initialisation when built-in
When mac80211 is built into the kernel it needs to init earlier
so that device registrations are run after it has initialised.
The same applies to rate control algorithms.

When I added the monitor for outgoing frames somehow a break
statement slipped in. Remove it.

fd8bacc980 [PATCH] mac80211: regulatory domain cleanup
Currently, a function misnamed ieee80211_init_client() is used to handle
regulatory domain control. It is called from
ieee80211_register_hwmode(), which typically runs 2 or 3 times
(802.11a/b/g), but each time it iterates over all the modes.

This patch cleans this up and removes the confusion:
ieee80211_init_client was effectively renamed to
ieee80211_set_default_regdomain and is now run on a per-mode basis
(doesn't have to deal with netdevs). I also moved the regdomain handling
code into its own file and added some documentation.

63fc33ceb0 [PATCH] mac80211: improved 802.11g CTS protection
Currently, CTS protection is partially implemented twice:
 1. via prism2 ioctls, only used by hostapd
 2. via STA beacon parsing, recorded in sta.use_protection but never used
    (other than printed in debugfs)

Protection control should be implemented on a per-subif basis. For example,
a single physical device may be running a soft AP on one channel, and a STA
on another. The AP interface should use protection based on what hostapd told
it, and the STA interface should use protection based on beacon parsing.
These should operate independantly: one subif using protection should not
influence the other.

To implement this, I moved the use_protection flag into ieee80211_sub_if_data
and removed the device-global cts_protect_erp_frames flag.

I also made the PRISM2_PARAM_CTS_PROTECT_ERP_FRAMES write operation only
available for AP interfaces, to avoid any possibility of the user messing with
the behaviour of a STA.

4480f15ca6 [PATCH] mac80211: clarify some mac80211 things
The semantics of not having an add_interface callback are not well
defined, this callback is required because otherwise you cannot obtain
the requested MAC address of the device. Change the documentation to
reflect this, add a note about having no MAC address at all, add a
warning that mac_addr in struct ieee80211_if_init_conf can be NULL and
finally verify that a few callbacks are assigned by way of BUG_ON()

3ef8bed469 [PATCH] mac80211: kill rate control ioctls
These aren't used anywhere (hostapd, wpa_supplicant) and until we
have a proper interface to the rate control algorithms they don't
make much sense either since e.g. rc80211_lowest won't honour them.

This patch makes mac80211 show transmitted frames on monitor interfaces,
including radiotap headers that indicate some transmission parameters.
The shown parameters will need to be expanded, but this should work as
a basis to work from.
