2014-01-13iwlwifi: pcie: enable oscillator for L1 exitEmmanuel Grumbach
Enabling the oscillator consumes slightly more power (100uA) but allows to make sure that we exit from L1 on time. Not doing so might lead to a PCIe specification violation since we might wake up from L1 at the wrong time. This issue has been identified on 3160 and 7260 only. On older NICs L1 off is not enabled, on newer NICs (7265), the issue is fixed. When the bug occurs the user sees that the NIC has disappeared from the PCI bridge, any access to the device returns 0xff.

2014-01-13ath9k: Process GTT interruptsSujith Manoharan
Global Transmission Timeout interrupts are generated by the HW when transmission of a frame fails - this is done based on the threshold programmed in the AR_GTXTO register. Currently, even though the interrupt is enabled for all chips, it is not handled in the driver. This patch handles GTT events for AR9003 and above chips, checking if the MAC/BB has hung after successive GTT interrupts crosses a threshold (5). This can be enabled for the older chips in the AR9002 family once appropriate HW hang checks are implemented for them.
