* nl80211: make get_vlan logic more commonJohannes Berg2011-11-21
| | | | | | | | | get_vlan() sets the output parameter even if it returns an error, which is a bit odd. Instead, convert it to use ERR_PTR. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* cfg80211: add flags for off-channel capabilitiesJohannes Berg2011-11-21
| | | | | | | | | | | Currently mac80211 implements these for all devices, but given restrictions of some devices that isn't really true, so prepare for being able to remove the capability for some mac80211 devices.

* mac80211: minor cleanup to mesh state lockingJohannes Berg2011-11-21
| | | | | | | | | | | | | First time I tried smatch, and it says: mesh_hwmp.c +870 mesh_queue_preq(21) error: double lock 'bottom_half:' mesh_hwmp.c +873 mesh_queue_preq(24) error: double unlock 'bottom_half:' mesh_hwmp.c +886 mesh_queue_preq(37) error: double unlock 'bottom_half:' Which is indeed true -- there's no point in disabling BHs again if we just did that a few lines earlier, so remove.

* iwl-debug: Shrink object by using dev_err and deduplicating formatsJoe Perches2011-11-21
| | | | | | | | | | | | | | | | | | | Using dev_err instead of dev_printk(KERN_ERR uses fewer arguments and is a bit smaller. Deduplicating formats used by IWL_DEBUG_QUIET_RFKILL also makes the object a bit smaller.

* rtlwifi: Remove redundant code from PCI interruptLarry Finger2011-11-21
| | | | | | | | The interrupt routine for PCI devices has a special exit that executes the same instructions as does the normal exit. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* rtlwifi: rtl8192cu: Fix endianian issuesLarry Finger2011-11-21
| | | | | | | | | | | | | | Driver rtlwifi fails on a big-endian host. These changes have been tested on a Mac PowerBook G4, which has a PPC processor. Although this patch touches some of the code that will affect endian issues on PCI hardware through drivers rtl8192ce, rtl8192se, and rtl8192de, these have not been tested due to lack of suitable hardware. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* rtlwifi: rtl8192cu: Change firmware upload to use block writesLarry Finger2011-11-21
| | | | | | | | | | Driver rtl8192cu writes the firmware with 32-bit asynchronous writes. This design is OK for USB 2.0 adapters, but the current implementation of xhcu-hcd has a limited ring size, which is exceeded. By converting to synchronous block writes, this error is avoided.

* rtlwifi: rtl8192cu: Allow retries for USB I/OGeorge2011-11-21

* nl80211: add testmode to the list of supported commandsKalle Valo2011-11-21
| | | | | | | | | | | User space might want to test if driver supports testmode. Adding testmode to the list of supported commands makes this easier. I omitted testmode_dump() in purpose. I assume all drivers implementing testmode_dump() will also implement testmode_cmd(). Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* mac80211: remove unused ASSOC_AP flagJohannes Berg2011-11-21
| | | | | | | | | WLAN_STA_ASSOC_AP indicates that the station entry is for an AP we're associated to but isn't used so remove it. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* mac80211: transmit fragment list to driversJohannes Berg2011-11-21
| | | | | | | | | | | | | | Drivers can usually handle fragmented packets much easier when they get the entire list of fragments at once. The only thing they need to do is keep enough space on the queues for up to ten fragments of a single MSDU. This allows them to implement this with a new operation tx_frags. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* mac80211: make TX LED handling independent of fragmentationJohannes Berg2011-11-21
| | | | | | | | | | This just prepares for passing the entire fragment list to the driver. No significant changes, but the TX throughput is calculated slightly differently now and we blink only once for each MSDU. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* mac80211: move fragment flag adjustmentJohannes Berg2011-11-21
| | | | | | | | Instead of adjusting the fragment flags at TX time, adjust them at fragmentation time. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* mac80211: use skb list for fragmentsJohannes Berg2011-11-21
| | | | | | | | | | | | | We are currently linking the skbs by using skb->next directly. This works, but the preferred way is to use a struct sk_buff_head instead. That also prepares for passing that to drivers directly. While at it I noticed we calculate the duration for fragments twice -- remove one of them.

* ath9k: trivial: reorder rx_tasklet processingZefir Kurtisi2011-11-21
| | | | | | | | | | | | DFS events are reported as PHY errors and need to be processed with a correct timestamp set before ath9k_skb_preprocess() is called and the frame is possibly dropped. This patch puts the rxs->mactime calculation before the skb is preprocessed to prepare for DFS event reporting. Signed-off-by: Zefir Kurtisi <zefir.kurtisi@neratec.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* cfg80211: pass DFS region to drivers through reg_notifier()Luis R. Rodriguez2011-11-21

* cfg80211: process regulatory DFS region for countriesLuis R. Rodriguez2011-11-21
| | | | | | | | | | | The wireless-regdb now has support for mapping a country to one DFS region. CRDA sends this to us now so process it so we can provide that hint to drivers. This will later be used by code for processing DFS in a way that meets the criteria for the DFS region the country belongs to. Signed-off-by: Luis R.
