* mac80211: allow controlling aggregation manuallyJohannes Berg2010-05-03
| | | | | | | | | | | | | | | | | This allows enabling TX and disabling both TX and RX aggregation sessions manually in debugfs. It is very useful for debugging session initiation and teardown problems since with this you don't have to force a lot of traffic to get aggregation and thus have less data to analyse. Also, to debug mac80211 code itself, make hwsim "support" aggregation sessions. It will still just transfer the frame, but go through the setup and teardown handshakes.

* orinoco_usb: implement fw downloadDavid Kilroy2010-05-03

* orinoco: add orinoco_usb driverDavid Kilroy2010-05-03
| | | | | | | | | | | | | | | | | This driver uses the core orinoco modules for the bulk of the functionality. The low level hermes routines (for local bus cards) are replaced, the driver supplies its own ndo_xmit_start function, and locking is done with the _bh variant. Some recent functionality is not available to the USB cards yet (firmware loading and WPA). Out-of-tree driver originally written by Manuel Estrada Sainz. Thanks to Mark Davis for supplying hardware to test the updates. Signed-off-by: David Kilroy <kilroyd@googlemail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* orinoco: encapsulate driver lockingDavid Kilroy2010-05-03
| | | | | | | | | | | | | | | Local bus and USB drivers will need to do locking differently. The original orinoco_usb patches had a boolean variable controlling whether spin_lock_bh was used, or irq based locking. This version provides wrappers for the lock functions and the drivers specify the functions pointers needed. This will introduce a performance penalty, but I'm not expecting it to be noticable.

* orinoco: allow driver to specify netdev_opsDavid Kilroy2010-05-03
| | | | | | | | | | | | Allow the main drivers to specify a custom version of the net_device_ops structure. This is required by orinoco_usb to supply a separate transmit function.

* iwl: cleanup: remove unneeded error handlingDan Carpenter2010-04-28
| | | | | | | | | | | | | | | | | | | | | | This is just a cleanup and doesn't change how the code works. debugfs_create_dir() and debugfs_create_file() return an error pointer (-ENODEV) if CONFIG_DEBUG_FS is not enabled, otherwise if an error occurs they return NULL. This is how they are implemented and what it says in the DebugFS documentation. DebugFS can not be compiled as a module. As a result, we only need to check for error pointers and particularly -ENODEV one time to know that DebugFS is enabled. This patch keeps the first check for error pointers and removes the rest. The other reason for this patch, is that it silences some Smatch warnings. Smatch sees the condition "(result != -ENODEV)" and assumes that it's possible for "result" to equal -ENODEV. If it were possible it would lead to an error pointer dereference. But since it's not, we can just remove the check. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: John W.

* rt2x00: rt2800lib: update rfcsr & bbp init code for SoC devicesHelmut Schaa2010-04-28
| | | | | | | | | | | | | | | | | | Update the rfcsr and bbp init code for SoC devices to match with the latest Ralink driver. To have better control over which values are used for the register initialization create a new function rt2800_is_305x_soc which checks for SoC interface type, the correct RT chipset and the correct RF chipset. This is based on the assumption that all rt305x SoC devices use a rt2872 and rf3020/rf3021/rf3022. In case an unknown RF chipset is found on a SoC device with a rt2872 don't treat it as rt305x and just print a message.

* wl1271: Rewrite hardware keep-alive handlingJuuso Oikarinen2010-04-28
| | | | | | | | | | | | | | | | The driver had a join command without keep-alive restart procedures in the channel changing code. After associated scans, the mac80211 does re-set the current channel, causing the join to occur. This would stop the hardware keep alive. To make the joins safer in this respect, this patch adds a join function that does the hardware-keep-alive magic along the join. This is now invoked in the above mentioned scenario, and also other scenarios.

* wl1271: Improve command pollingJuuso Oikarinen2010-04-28
| | | | | | | | | | | | | | | | In testing I noticed that the wl1271 commands fall into two categories. In the first category are "fast" commands, these mostly take only 0 or 1 polls to complete, but occasionally upto 50 (giving a 0.5ms execution time.) In the second category, the command completion takes well more than 0.5ms (from 1.5ms upwards.) This patch fixes command polling such that it is optimal for the fast commands, but also allows sleep for the longer ones.

* mac80211: fix rts threshold checkShanyu Zhao2010-04-27
| | | | | | | | | | | | | | | | | | | | Currently whenever rts thresold is set, every packet will use RTS protection no matter its size exceeds the threshold or not. This is due to a bug in the rts threshold check. if (len > tx->local->hw.wiphy->rts_threshold) { txrc.rts = rts = true; } Basically it is comparing an int (len) and a u32 (rts_threshold), and the variable len is assigned as: len = min_t(int, tx->skb->len + FCS_LEN, tx->local->hw.wiphy->frag_threshold); However, when frag_threshold is "-1", len is always "-1", which is 0xffffffff therefore rts is always set to true.
