2012-12-10rt2800usb: Add support for 2001:3c1e (D-Link DWA-125 rev B1) USB Wi-Fi adapterMaia Kozheva1-0/+1
D-Link DWA-125/B1 is a relatively new USB Wi-Fi adapter, using a Ralink chipset supported by the rt2800usb driver. Currently, to work around the problem (it's missing in all present kernel versions, up to and including 3.7.x), I had to add this to /etc/rc.local: echo 2001 3c1e >> /sys/bus/usb/drivers/rt2800usb/new_id After that, the device works without problems. Been using it for over a week with no bugs in sight. The attached patch is trivial and simply adds the new USB ID to the list of devices handled by rt2800usb.

2012-12-03rt2x00: rt2800lib: introduce RFCSR3_VCOCAL_ENGabor Juhos2-2/+4
On the RF3290,RF5360,RF5370,RF5372,RF5390,RF5392 radio frontends, the VCO calibration can be controlled via the RFCSR3 register. The current code uses the RFCSR30_RF_CALIBRATION constant to enable the calibration, however that belongs to the RFCSR30 register. Although the values of the constant is correct, but using that for another register is confusing. Add a new definition for the VCO calibration enable bit of the RFCSR3 register and use that in the relevant places in order to avoid confusions. The patch contains no functional changes.

During hardware restart, all interfaces are iterated even though they haven't been re-added to the driver, document this behaviour. The same also happens during resume, which is even more confusing since all of the interfaces were previously removed from the driver. Make this optional so drivers relying on the current behaviour can still use it, but to let drivers that don't want this behaviour disable it.

Patch fixes warnings like below happened on resume: WARNING: at net/mac80211/driver-ops.h:12 check_sdata_in_driver+0x32/0x34() Problem is that in __ieee80211_susped() we remove sdata (i.e wlan0 interface) and then during resume we call usb_unbind_interface() -> ieee80211_unregister_hw() with sdata removed. Patch fixes problem by adding .reset_resume calback, hence we do not unbind usb device on resume. This callback can be the same as normal .resume callback, sice we do all needed initalization during interface start, which is performed on resume [ ieee80211_resume() -> ieee80211_reconfig() -> rt2x00mac_start() -> rt2x00lib_start ].

2012-07-12mac80211: add time synchronisation with BSS for assocJohannes Berg1-1/+1
Some drivers (iwlegacy, iwlwifi and rt2x00) today use the bss_conf.last_tsf value. By itself though that value is completely worthless since it may be ancient. What really is needed is synchronisation between some device time and the TSF. To clarify this, rename bss_conf.last_tsf to sync_tsf and add sync_device_ts which is obtained from rx_status which gets a new field device_timestamp for this purpose. This is intentionally not using the mactime field since that is used for other things and in IBSS is expected to sync with the IBSS's TSF which isn't necessarily true for the device timestamp. Also, since we have the information and it's useful even before the connection has been established, give all the timing details to the driver before authenticating.
