2015-02-06ath9k: Choose correct rate for 2GHz channelSujith Manoharan1-1/+5

2015-02-06ath9k: Fix issues with WoW enableSujith Manoharan3-95/+93
This patch addresses several issues with the ath9k_hw_wow_enable() routine: * The usage of set/clr variables is removed. Writing the required values to registers is cleaner. * The shift value of 28 for the contention window field in AR_WOW_PATTERN is incorrect, change it to 27. * Disabling Keep Alive needs to be done based on the LINK_CHANGE option. This is done unconditionally now, fix this. * The workaround for the D1/D3 issue is required only for AR9462. * The bitfield for enabling pattern matching for packets less than 256 bytes has expanded for new chips, handle this accordingly. * General cleanup.

2015-02-06ath9k: Register correct WOW details with mac80211Sujith Manoharan1-2/+14

2015-02-06ath9k: Add support for more WOW patternsSujith Manoharan3-27/+56
Newer chips like WB222, WB335 support more than 8 user-configurable patterns. This patch adds support for it by setting up the correct HW registers. Signed-off-by: Sujith Manoharan <[email protected]> Signed-off-by: Kalle Valo <[email protected]>
2015-02-06rtlwifi: rtl8192ee: Fix problems with calculating free space in FIFOLarry Finger2-8/+8
This driver utilizes a FIFO buffer for RX descriptors. There are four places in the code where it calculates the number of free slots. Several of those locations do the calculation incorrectly. To fix these and to prevent future mistakes, a common inline routine is created.

2015-02-06rtlwifi: rtl8192ee: Fix handling of new style descriptorsTroy Tan5-10/+46
The hardware and firmware for the RTL8192EE utilize a FIFO list of descriptors. There were some problems with the initial implementation. The worst of these failed to detect that the FIFO was becoming full, which led to the device needing to be power cycled. As this condition is not relevant to most of the devices supported by rtlwifi, a callback routine was added to detect this situation. This patch implements the necessary changes in the pci handler, and the linkage into the appropriate rtl8192ee routine.

2015-02-05ixgbevf: combine all of the tasks into a single service taskEmil Tantilov2-66/+87
This change combines the reset and watchdog tasklets into a single task. The advantage of this is that we can avoid multiple schedules of the reset task when we have a reset event needed due to either the mailbox going down or transmit packets being present on a link down.

2015-02-05ixgbevf: rewrite watchdog task to function similar to igbvfEmil Tantilov2-75/+113
This patch cleans up the logic dealing with link down/up by breaking down the link detection and up/down events into separate functions - similar to how these events are handled in other drivers.

2015-02-05ixgbevf: Add code to check for Tx hangEmil Tantilov2-19/+115
This patch adds code to allow for Tx hang checking. The idea is to provide more robust debug info in the event of a transmit unit hang. Similar to the logic in ixgbe.

2015-02-05ixgbevf: Fix ordering of shutdown to correctly disable Rx and TxEmil Tantilov1-21/+17
This patch updates the ordering of the shutdown path so that we attempt to shutdown the rings more gracefully. Basically the big changes are that we shutdown the main Rx filter in the case of Rx and we set the carrier_off state in the case of Tx so that packets stop being delivered from outside the driver. Then we shut down interrupts and NAPI. Finally we stop the rings from performing DMA and clean them. This is a bit more graceful than the previous path.

2015-02-05ixgbe: Cleanup probe to remove redundant attempt to ID PHYDon Skidmore1-3/+0
We always identify the PHY in our reset_hw path anyway so there is no need to do it in get_invariants(). The reason I even noticed this is that for new hardware (X550em) we don't assign some methods until later in probe and calling phy.ops.read_reg could lead to a panic.

Conflicts: drivers/net/vxlan.c drivers/vhost/net.c include/linux/if_vlan.h net/core/dev.c The net/core/dev.c conflict was the overlap of one commit marking an existing function static whilst another was adding a new function. In the include/linux/if_vlan.h case, the type used for a local variable was changed in 'net', whereas the function got rewritten to fix a stacked vlan bug in 'net-next'. In drivers/vhost/net.c, Al Viro's iov_iter conversions in 'net-next' overlapped with an endainness fix for VHOST 1.0 in 'net'. In drivers/net/vxlan.c, vxlan_find_vni() added a 'flags' parameter in 'net-next' whereas in 'net' there was a bug fix to pass in the correct network namespace pointer in calls to this function.
