Kyeyoon Park fa9ffc7456 cfg80211: Add support for QoS mapping
This allows QoS mapping from external networks to be implemented as
defined in IEEE Std 802.11-2012, 10.24.9. APs can use this to advertise
DSCP ranges and exceptions for mapping frames to a specific UP over
Wi-Fi.

The payload of the QoS Map Set element (IEEE Std 802.11-2012, 8.4.2.97)
is sent to the driver through the new NL80211_ATTR_QOS_MAP attribute to
configure the local behavior either on the AP (based on local
configuration) or on a station (based on information received from the
AP).

Bing Zhao 82efa16ad2 mwifiex: download per country tx power table to firmware
When driver gets regulatory domain change notifications or before
associates to an AP with Country IE, the txpwrlimit table stored
in device tree for that country is downloaded to firmware.

The txpwrlimit downloading will happen only at the first time
when the alpha2 country code is changed. World regulatory domain
"00" notification doesn't trigger the downloading. This behavior
is same as domain_info command.

On cfg80211 regulatory domain change, drivers gets alpha2 country

These two flags are used for the same purpose, just
combine them into a no-ir flag to annotate no initiating

Old userspace sending either flag will have it treated as
the no-ir flag. To be considerate to older userspace we
also send both the no-ir flag and the old no-ibss flags.
Newer userspace will have to be aware of older kernels.

Update all places in the tree using these flags with the

Dan Carpenter 95edbc30db mwifiex: potential integer underflow in mwifiex_ret_wmm_get_status()
Before we loop for next iteration we adjust the buffer pointer and
"resp_len":

		curr += (tlv_len + sizeof(tlv_hdr->header));
		resp_len -= (tlv_len + sizeof(tlv_hdr->header));

If "resp_len" gets set to negative then it counts as a high positive
value.

Avinash Patil 9612bd1ee3 mwifiex: inform cfg80211 about disconnect for P2P client interface

Avinash Patil e8041ceede mwifiex: inform cfg80211 about disconnect if device is removed
If device is surprise removed, commands sent to FW including
deauthenticate command fail as bus writes fail.
We update our media_connected status to false and inform cfg80211
about disconnection only when command is successful. Since cfg80211
assumes device is still connected, it results into following
WARN_ON during unload:

WARNING: CPU: 0 PID: 18245 at net/wireless/core.c:937
         cfg80211_netdev_notifier_call+0x175/0x4d0 [cfg80211]()

Avoid this by emitting cfg80211_disconnected event even if the
deauthenticate command fails.

Peter Senna Tschudin c856197d6e mwifiex: Change variable type to bool
The variables cancel_scan_cmd, enable_data, hs_activate and valid are
only assigned the values true and false. Change its type to bool.

The simplified semantic patch that find this problem is as
follows (http://coccinelle.lip6.fr/):

@exists@
type T;
identifier b;
@@
- T
+ bool
  b = ...;
  ... when any
  b = \(true\|false\)
