Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

* rt2x00: rt73usb: use rt2x00_has_cap_* helpersGabor Juhos2013-10-141-9/+9

* rt2x00: read 5GHz TX power values from the correct offsetGabor Juhos2013-06-241-1/+2
| | | | | | | | | | | | | | | | | | | The current code uses the same index value both for the channel information array and for the TX power table. The index starts from 14, however the index of the TX power table must start from zero. Fix it, in order to get the correct TX power value for a given channel. The changes in rt61pci.c and rt73usb.c are compile tested only.

| | | | | | | | | | | | | | | | | The extra_tx_headroom field of struct rt2x00_ops indicates the extra TX headroom size required for a given device.

| | | | | | | | | | | | | | | | | | | | | | | | | | 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 ].

| * USB: Disable hub-initiated LPM for comms devices.Sarah Sharp2012-05-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hub-initiated LPM is not good for USB communications devices. Comms devices should be able to tell when their link can go into a lower power state, because they know when an incoming transmission is finished. Ideally, these devices would slam their links into a lower power state, using the device-initiated LPM, after finishing the last packet of their data transfer. If we enable the idle timeouts for the parent hubs to enable hub-initiated LPM, we will get a lot of useless LPM packets on the bus as the devices reject LPM transitions when they're in the middle of receiving data. Worse, some devices might blindly accept the hub-initiated LPM and power down their radios while they're in the middle of receiving a transmission. The Intel Windows folks are disabling hub-initiated LPM for all USB communications devices under a xHCI USB 3.0 host. In order to keep the Linux behavior as close as possible to Windows, we need to do the same in Linux. Set the disable_hub_initiated_lpm flag for for all USB communications drivers. I know there aren't currently any USB 3.0 devices that implement these class specifications, but we should be ready if they do.

To best support the set_antenna callback some modifications are needed in the diversity handling. We should never look at the default antenna settings to determine if software diversity is enabled. Instead we should set the diversity flag when possible, which will allow the link_tuner to automatically pick up the tuning.

| | | | | | | | | | | | | | | | | | | | | | Both USB and PCI drivers allow a system administrator to dynamically add USB/PCI IDs to the device table that a driver supports via the /sys/bus/{usb,pci,pci_express}/drivers/<driver-name>/new_id files. However, for the rt2x00 drivers using this method currently crashes the system with a NULL pointer failure. This is due to the set-up of rt2x00 where the probe functions require a rt2x00_ops structure in the driver_info field of the probed device. As this field is empty for the dynamically added devices this fails for these devices. Fix this by introducing driver-specific probe wrappers that do nothing but calling the bus-specific probe functions with the rt2x00_ops structure as an argument, rather than depending on the driver_info field.

* rt2x00: Split rt2x00dev->flagsIvo van Doorn2011-04-191-16/+16
| | | | | | | | | | | | | | | | | | | | | | | | The number of flags defined for the rt2x00dev->flags field, has been growing over the years. Currently we are approaching the maximum number of bits which are available in the field. A secondary problem, is that one part of the field are initialized only during boot, because the driver requirements are initialized or device requirements are loaded from the EEPROM. In both cases, the flags are fixed and will not change during device operation. The other flags are the device state, and will change frequently. So far this resulted in the fact that for some flags, the atomic bit accessors are used, while for the others the non-atomic variants are used. By splitting the flags up into a "flags" and "cap_flags" we can put all flags which are fixed inside "cap_flags". This field can then be read non-atomically. In the "flags" field we keep the device state, which is going to be read atomically. This adds more room for more flags in the future, and sanitizes the field access methods.

* rt2x00: Refactor beacon code to make use of start- and stop_queueHelmut Schaa2011-01-311-14/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows to dynamically remove beaconing interfaces without shutting beaconing down on all interfaces. The only place to start and stop beaconing are now the start- and stop_queue callbacks. Hence, we can remove some register writes during interface bring up (config_intf) and only write the correct sync mode to the register there. When multiple beaconing interfaces are present we should enable beaconing as soon as mac80211 enables beaconing on at least one of them. The beacon queue gets stopped when the last beaconing interface was stopped by mac80211. Therefore, introduce another interface counter to keep track ot the number of enabled beaconing interfaces and start or stop the beacon queue accordingly. To allow single interfaces to stop beaconing, add a new driver callback clear_beacon to clear a single interface's beacon without affecting the other interfaces. Don't overload the clear_entry callback for clearing beacons as that would introduce additional overhead (check for each TX queue) into the clear_entry callback which is used on the drivers TX/RX hotpaths. Furthermore, the write beacon callback doesn't need to enable beaconing anymore but since beaconing should be disabled while a new beacon is written or cleared we still disable beacon generation and enable it afterwards again in the driver specific callbacks. However, beacon related interrupts should not be disabled/enabled here, that's solely done from the start- and stop queue callbacks. It would be nice to stop the beacon queue just before the beacon update and enable it afterwards in rt2x00queue itself instead of the current implementation that relies on the driver doing the right thing. However, since start- and stop_queue are mutex protected we cannot use them for atomic beacon updates.

| | | | | | | | | | | | | | | | | | | | | | | | | As part of the queue refactoring, we now introduce 3 queue commands: start, kick, stop. - Start: will enable a queue, for TX this will not mean anything, while for beacons and RX this will update the registers to enable the queue. - Kick: This will kick all pending frames to the hardware. This is needed for the TX queue to push all frames to the HW after the queue has been started - Stop: This will stop the queue in the hardware, and cancel any pending work (So this doesn't mean the queue is empty after a stop!). Move all code from the drivers into the appropriate functions, and link those calls to the old rt2x00lib callback functions (we will fix this later when we refactor the queue control inside rt2x00lib).

However, due to a bug in rt2800usb and rt2800pci the beacon interval was reset during each scan, thus causing problems in AdHoc mode. Fix this by not cleaning up the beacon interval when killing the beacon queue but just prevent the device from sending out beacons.
