The rtnl is held in ieee80211_sta.c to prevent some potential
configuration races with userspace. Unfortunately, it also has the
potential for deadlocks on interface down. This patch removes the
rtnl locking to eliminate the deadlocks.Signed-off-by: Michael Wu

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.Signed-off-by: Daniel Drake

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.Signed-off-by: Daniel Drake

The "protection needed" flag is currently parsed out of the ERP IE in
beacons. This patch allows the ERP IE to be available at assocation time
and causes the appropriate actions to be performed earlier.It is slightly complicated by the fact that most APs don't include the
ERP IE in association responses. To work around this, we store ERP
values in the ieee80211_sta_bss structure.Also added some WLAN_ERP defines for use by upcoming patches.

The WEXT ioctl SIOCSIWRATE is not implemented in mac80211. This patch
adds the missing routine. It supports the 'auto' keyword, fixed rates,
and the combination of 'auto' and a fixed rate to select an upper bound.Based on the patch from Mohamed Abbas .

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()Signed-off-by: Johannes Berg

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.Signed-off-by: Johannes Berg

The initial rate for STA's using rc80211_simple is set to the last
rate in the rate table. For situations for which the signal is weak,
the rate may be too high for authentication and association. Although
the rc80211_simple module will adjust the speed, the response may not
be fast enough for a successful connection. This modification sets the
initial rate to the lowest supported value.Signed-off-by: Larry Finger

At present, transmission rate information for mac80211 is available only
if verbose debugging is turned on, and then only in the logs. This patch

mac80211 stops the tx queues during scans. This is wrong with respect
to the master deivce tx queue, since stopping it prevents any probes
from being sent during the scan. Instead, they accumulate in the queue
and are only sent after the scan is finished, which is obviously
wrong.Signed-off-by: Mattias Nissler

Some APs have strict checking between associate and reassociate. In
a case when an AP is restarted during a connection, it denies the
mac80211 reassoc request since this is a new association for the AP.
To fix this problem, we need to check the status code against
WLAN_STATUS_REASSOC_NO_ASSOC and clear ifsta->prev_bssid_set in
handling the association failure response.Signed-off-by: Zhu Yi
