2013-08-26rt2800: fix wrong TX power compensationStanislaw Gruszka
We should not do temperature compensation on devices without EXTERNAL_TX_ALC bit set (called DynamicTxAgcControl on vendor driver). Such devices can have totally bogus TSSI parameters on the EEPROM, but still threaded by us as valid and result doing wrong TX power calculations. This fix inability to connect to AP on slightly longer distance on some Ralink chips/devices.

2013-08-26ath9k: Fix ASPM workaround usageSujith Manoharan
The PCIE Workaround register (AR_WA/0x4004) is used to handle various hardware quirks. For AR9002 chips, AR_WA_D3_L1_DISABLE is used to prevent the HW from automatically entering L1 state when D3 is enforced. AR_WA_D3_L1_DISABLE has to be enabled for a few AR9280 based cards, mark them based on their PCI subdevice/subvendor IDs and enforce it in ar9002_hw_configpcipowersave().

2013-08-26mwifiex: fix driver unload problem for usb chipsetsAmitkumar Karwar
We have usb_deregister() call in our rmmod routine. deauth, shutdown etc. commands will be sent to FW later when bus driver calls disconnect handler. This mechanism works fine with SDIO and PCIe interfaces, but there is an issue with USB. USB bus driver returns all URBs submitted for receiving data and command response immediately after usb_deregister() with failure status. Hence we don't send deauth, shutdown etc. command to firmware. The problem is fixed by moving code from disconnect handler to rmmod routine for USB interface.

On devices which have selectable shared memory parts, some beacon may be located in the high part of the shared memory. Instead of extending the already complicated macro, add a new helper function and use that to get the base address of a given beacon. The actual patch contains no functional changes, the helper function will be extended in a further patch to handle different chipsets' requirements.

2013-08-22mwifiex: do not create AP and P2P interfaces upon driver loadingBing Zhao
Bug 60747 - 1286:2044 [Microsoft Surface Pro] Marvell 88W8797 wifi show 3 interface under network https://bugzilla.kernel.org/show_bug.cgi?id=60747 This issue was also reported previously by OLPC and some folks from the community. There are 3 network interfaces with different types being created when mwifiex driver is loaded: 1. mlan0 (infra. STA) 2. uap0 (AP) 3. p2p0 (P2P_CLIENT) The Network Manager attempts to use all 3 interfaces above without filtering the managed interface type. As the result, 3 identical interfaces are displayed under network manager. If user happens to click on an entry under which its interface is uap0 or p2p0, the association will fail. Work around it by removing the creation of AP and P2P interfaces at driver loading time. These interfaces can be added with 'iw' or other applications manually when they are needed.

2013-08-22ath9k_htc: Restore skb headroom when returning skb to mac80211Helmut Schaa
ath9k_htc adds padding between the 802.11 header and the payload during TX by moving the header. When handing the frame back to mac80211 for TX status handling the header is not moved back into its original position. This can result in a too small skb headroom when entering ath9k_htc again (due to a soft retransmission for example) causing an skb_under_panic oops. Fix this by moving the 802.11 header back into its original position before returning the frame to mac80211 as other drivers like rt2x00 or ath5k do.
