2014-05-29wil6210: limit fw error recovery attemptsVladimir Kondratiev
In case there is something fundamentally wrong with the firmware (example: RF cable disconnected), FW will always crash immediately after reset. This leads to infinite fw error recovery loop. Count consecutive unsuccessful error recovery attempts in a short period of time, and stop doing recovery after some reasonable count. It is still possible to manually reset fw doing interface down/up sequence. Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2014-05-29at76c50x-usb: Make WEP encryption working.Andrea Merello
Currently the driver uses HW encryption. Whenever mac80211 calls the set_key() callback the driver restarts the whole HW configuration procedure, in order to set (also) the new WEP key. However, by doing this, it causes the card to loose association information, and the HW becomes unable to communicate with the BSS. This patch adds support for sending another HW command, that sets only the wep key, instead of resetting all. Mac80211 key-set requests are thus handled via this new command.

2014-05-29i40e: relax the firmware API version checkShannon Nelson

The API changes minor numbers when things get added to the API, but no existing structs or calls are changed. The driver has the option of warning that the minor numbers don't match. This will allow a little more flexibility in handling newer NICs and NVMs in the field.

2014-05-27can: only rename enabled led triggers when changing the netdev nameOliver Hartkopp
Commit a1ef7bd9fce8 ("can: rename LED trigger name on netdev renames") renames the led trigger names according to the changed netdevice name. As not every CAN driver supports and initializes the led triggers, checking for the CAN private datastructure with safe_candev_priv() in the notifier chain is not enough. This patch adds a check when CONFIG_CAN_LEDS is enabled and the driver does not support led triggers.

2014-05-27ath10k: abort incomplete scatter-gather pci tx properlyMichal Kazior
This prevents leaving incomplete scatter-gather transfer on CE rings which can lead firmware to crash. Reported-By: Avery Pennarun <apenwarr@gmail.com> Signed-off-by: Michal Kazior <michal.kazior@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2014-05-27ath10k: protect src_ring state with ce_lock in tx_sg()Michal Kazior
It was possible to read invalid state of CE ring buffer indexes. This could lead to scatter-gather transfer failure in mid-way and crash firmware later by leaving garbage data on the ring.

It seems ath10k firmware gives us no way to know the rssi for rx-fragments. Signed-off-by: Ben Greear <greearb@candelatech.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2014-05-27ath10k: dont configure bssid for ap modeMichal Kazior
FW creates self-peer for AP internally. This prevents ath10k from trying to create explicit self-peer during hw recovery and thus prevents a timeout and a warning during teardown: ath10k: removing stale peer $AP_BSSID from vdev_id 0 Signed-off-by: Michal Kazior <michal.kazior@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2014-05-27ath10k: protect wep tx key setupMichal Kazior
All configuration sequences should be protected with conf_mutex to avoid concurrent/conflicting requests. This should make sure that wep tx key setup is not performed while hw is restarted (at least).
