2013-10-17net/mlx4_core: Load higher level modules according to ports typeEyal Perry
Mellanox ConnectX architecture is: mlx4_core is the lower level PCI driver which register on the PCI id, and protocol specific drivers are depended on it: mlx4_en - for Ethernet and mlx4_ib for Infiniband. NIC could have multiple ports which can change their type dynamically. We use the request_module() call to load the relevant protocol driver when needed: on loading time or at port type change event.

2013-10-16ath10k: remove unnecessary checksMichal Kazior
mac80211 interface iteration functions that were used originally iterated over interfaces that weren't re-added to the driver during recovery. Since internal vif list is now used it's safe to remove the safe-guard as internal vif list is based on add/remove_interface function which guarantees that vdev is created in FW before it is iterated over.

2013-10-16ath10k: fix scheduling while atomic config bugMichal Kazior
Recent HTC/WMI changes introduced the bug. ath10k was using _atomic iteration function with sleepable functions. mac80211 provides another iteration function but it cannot be safely called in hw_config() callback due to local->iflist_mtx being possibly acquired already. The patch uses internal vif list for iteration purposes and removes/refactors no longer necessary _iter functions.

2013-10-16ath10k: fix add_interface failure handlingMichal Kazior

2013-10-16ath10k: use workqueue to set WEP TX keyMichal Kazior
Recent WMI/HTC changes made it possible for WMI commands to sleep (if there's not enough HTC TX credits to submit a command). TX path is in an atomic context so calling WMI commands in it is wrong. This simply moves WEP key index update to a worker and fixes the 'scheduling while atomic' bug. This still leaves multiple WEP key handling laggy, i.e. some frames may be TXed with an old/different key (although recipient should still be able to RX them). kvalo: changed the title Signed-off-by: Michal Kazior <michal.kazior@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

2013-10-11net: smc91x: dont't use SMC_outw for fixing up halfword-aligned dataWill Deacon
SMC_outw invokes an endian-aware I/O accessor, which may change the data endianness before writing to the device. This is not suitable for data transfers where the memory buffer is simply a string of bytes that does not require any byte-swapping. This patches fixes the smc91x SMC_PUSH_DATA macro so that it uses the string I/O accessor for outputting the leading or trailing halfwords on halfword-aligned buffers.
