2013-07-22rt2x00: rt2800lib: add default_power3 field for three-chain devicesGabor Juhos2-0/+23
The actual code uses two default TX power values. This is enough for 1T and for 2T devices however on 3T devices another value is needed for the third chain. Add a new field to struct channel_info and initialize it from the 'rt2800_probe_hw_mode' function. Also modify the 'rt2800_config_channel' to handle the new field as well.

The TX power values in the EEPROM are using a different format for the RT3593 chip. The default TX power value uses bits 0..4 only. Bits 5..8 contains value for fine grained power control.

2013-07-22mwifiex: fix IRQ enable/disableDaniel Drake5-61/+57
During tear down (e.g. mwifiex_sdio_remove during system suspend), mwifiex left IRQs enabled for a significant period of time when it was unable to handle them correctly. This caused interrupt storms and interfered with the bluetooth interface on the same SDIO card. Solve this by disabling interrupts at the point when they can no longer be handled correctly, which is at the start of mwifiex_remove_card(). For cleanliness, we now enable interrupts in the mwifiex_add_card() path, to be symmetrical with the disabling of interrupts. We also couple the registration of the sdio IRQ handler with the actual enable/disable of interrupts at the hardware level. I also removed a write to this register in mwifiex_init_sdio which seemed pointless and won't cause any ill effects now that we only register the SDIO IRQ handler when we are ready to accept interrupts.

2013-07-18rtlwifi: Fix build errors for unusual casesLarry Finger10-35/+91
The present build configuration for the rtlwifi family of drivers will fail under two known conditions: (1) If rtlwifi is selected without selecting any of the dependent drivers, there are errors in the build. (2) If the PCI drivers are built into the kernel and the USB drivers are modules, or vice versa, there are missing globals. The first condition is fixed by never building rtlwifi unless at least one of the device drivers is selected. The second failure is fixed by splitting the PCI and USB codes out of rtlwifi, and creating their own mini drivers. If the drivers that use them are modules, they will also be modules. Although a number of files are touched by this patch, only Makefile and Kconfig have undergone significant changes. The only modifications to the other files were to export entry points needed by the new rtl_pci and rtl_usb units, or to rename two variables that had names that were likely to cause namespace collisions.

2013-07-17ath9k_htc: fix data race between request_firmware_nowait() callback and ↵Alexey Khoroshilov1-3/+6
suspend() ath9k_hif_usb_probe() requests firmware asynchronically and there is some initialization postponed till firmware is ready. In particular, ath9k_hif_usb_firmware_cb() callback initializes hif_dev->tx.tx_buf and hif_dev->tx.tx_pending lists. At the same time, ath9k_hif_usb_suspend() iterates that lists through ath9k_hif_usb_dealloc_urbs(). If suspend happens before request_firmware_nowait() callback is called, it can lead to oops. Similar issue could be in ath9k_hif_usb_disconnect(), but it is prevented using hif_dev->fw_done completion and HIF_USB_READY flag. The patch extends this approach to suspend() as well.

2013-07-17rtlwifi: Initialize power-setting callback for USB devicesLarry Finger4-13/+15
Commit a269913c5 entitled "rtlwifi: Rework rtl_lps_leave() and rtl_lps_enter() to use work queue" has two bugs for USB drivers. Firstly, the work queue in question was not initialized. Secondly, the callback routine used by this queue is contained within the file used for PCI devices. As a result, it is not available for architectures without PCI hardware.

2013-07-16iwlwifi: mvm: fix the ACK / CTS kill mask upon RSSI eventEmmanuel Grumbach1-0/+2
If a vif's RSSI gets good enough, we can enable reduced Tx power. If so, we need to update the ACK / CTS kill mask accordingly. Since the auditing for the interfaces was bad, we enabled reduced Tx power, but didn't update the ACK / CTS kill mask. This is harmless since the firmware is most likely to discard this setting anyway, but it is a good practice to update it.

Change power management implementation to support new host-device API containing uAPSD parameters. Verify FW support for this new API. Use the new power table command (0xA9) to configure power management. Use the legacy command (0x77) if FW does not support the new API. New file power_legacy.c is introduced for legacy implementation.

Due to a firmware bug, it crashes when the beacon interval is smaller than 16. Avoid this by refusing the station state change creating the AP station, causing mac80211 to abandon the attempt to connect to the AP, and eventually wpa_s to blacklist it.
