* mac80211: Update device channel in case of HW channel switch supportedShahar Levi2011-09-14
| | | | | | | | | | | The hw.conf.channel value is not updated properly for drivers that support HW channel switch. Since the switch is done entirely by the driver and we don't call ieee80211_hw_config(), this value remains untouched. This patch fixes that by setting the new channel directly in ieee80211_chswitch_work(). Signed-off-by: Shahar Levi <shahar_levi@ti.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* mac80211: Mesh data frames must have the QoS headerJavier Cardona2011-09-14

* mac80211: Start implementing QoS support for mesh interfacesJavier Cardona2011-09-14
| | | | | | | | | | | | | In order to support QoS in mesh, we need to assign queue mapping only after the next hop has been resolved, both for forwarded and locally originated frames. Also, now that this is fixed, remove the XXX comment in ieee80211_select_queue(). Also, V-Shy Ho reported that the queue mapping was not being applied to the forwarded frame (fwd_skb instead of skb). Fixed that as well. Signed-off-by: Javier Cardona <javier@cozybit.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* rt2x00: Avoid unnecessary uncachedHelmut Schaa2011-09-14

Hence, don't read the TX descriptor prior to writing it since we update all fields anyway.

* rt2x00: Remove incorrect led blinkHelmut Schaa2011-09-14
| | | | | | | | | | | | | | rt2800 devices are not capable of configuring arbitrary LED on/off periods. The LED_CFG register fields ON_PERIOD and OFF_PERIOD are only used by the hw when the LED mode is set to "blink upon TX". Hence, remove the blink callback. This will result in software emulation for LED blinking.

* mac80211: stop tx before doing hw config and rate updateRajkumar Manoharan2011-09-14
| | | | | | | | | | | | | | | The assumption is that during the hw config, transmission was already stopped by mac80211. Sometimes the AP can be switching b/w the ht modes due to intolerant or etc where STA is in the middle of transmission. In such scenario, buffer overflow was observed at driver side. And also before updating the rate control, the frames are continued to xmited with older rates. This patch ensures that the frames are always xmitted with updated rates and avoid buffer overflow.
