In Bluetooth there are no automatic updates of remote device names when they get changed on the remote side. Instead, it is a good idea to do a manual name request when a new connection gets created (for whatever reason) since at this point it is very cheap (no costly baseband connection creation needed just for the sake of the name request). So far userspace has been responsible for this extra name request but tighter control is needed in order not to flood Bluetooth controllers with two many commands during connection creation. It has been shown that some controllers simply fail to function correctly if they get too many (almost) simultaneous commands during connection creation. The simplest way to acheive better control of these commands is to move their sending completely to the kernel side. This patch inserts name requests into the sequence of events that the kernel performs during connection creation. It does this after the remote features have been successfully requested and before any pending authentication requests are performed. The code will work sub-optimally with userspace versions that still do the name requesting themselves (it shouldn't break anything though) so it is recommended to combine this with a userspace software version that doesn't have automated name requests.

This patch adds a single function that's responsible for requesting authentication for outgoing connections. This is preparation for the next patch which will add automated name requests and thereby move the authentication requests to a different location.

If a device is autosuspended an inability to resubmit URBs is to be expected. Check the error code and only log real errors. (Now that autosuspend is default enabled for btusb, those log messages were happening all the time e.g. with a BT mouse) Signed-off-by: Stefan Seyfried <seife+kernel@b1-systems.com> Signed-off-by: Oliver Neukum <oneukum@suse.de> Acked-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Gustavo F.

Remove a superfluous ieee80211_is_data check as that was checked a few lines before already and we wont't get here for non-data frames at all. Second, the frame was already converted to 802.3 header format and reading the fc and addr1 fields was only possible because the 802.3 header is short enough and didn't overwrite the relevant parts of the 802.11 header. Make the code more obvious by checking the ethernet header's h_dest field. Furthermore reorder the conditions to reduce the number of checks when dynamic powersave is not needed (AP mode for example).

All rt2x00 drivers except rt2800pci call ieee80211_tx_status() from a workqueue, which causes "NOHZ: local_softirq_pending 08" messages. To fix it, add ieee80211_tx_status_ni() similar to ieee80211_rx_ni() which can be called from process context, and call it from rt2x00lib_txdone(). For the rt2800pci special case a driver flag is introduced. Signed-off-by: Johannes Stezenbach <js@sig21.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* A diff between rfbuffer settings of turbo and non-turbo modes indicates there is a bit on bank 2 related to turbo operation (it's set on turbo modes). This bit is present on all radios except RF5413 that seems to have a completely different bank 2. Also since 2317 has the same rf-registers locations with 2425 and since the bit exists on 2317 I assume it also exists on 2425/2417). So in case we use turbo mode (40MHz) enable it on bank modification. Signed-off-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* Since we set antenna flags on phy init and ack bitrate mode on pcu init, there is no need to save/restore sta_id flags on ath5k_hw_reset.

* Add synth-only channel change for AR2413/5413. When we call ath5k_reset with a channel ath5k_hw_reset will first try to set channel on PHY while PHY is running instead of doing a normal full reset. To do this phy_init has to change to implement this functionality. * Clean up change_channel flag, what it really did was skip PCU registers when setting initvals. This is done because on reset PCU registers are not affected (except the registers we set in pcu init and -due to hw problems- TSF). Use a new skip_pcu flag that's not misleading instead. In the future we might use that to also skip PCU reset and save us the TSF etc problems (needs testing because standard practice is to reset everything). * Use fast channel change only when setting channel, and set skip_pcu to false only on init. When we reset the card due to DMA or PHY problems skip pcu but never do a fast channel change. Signed-off-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W.

* Since we only use ath5k_hw_stop_tx_dma to stop the beacon queue, introduce a new function ath5k_hw_stop_beacon_queue so that we can use that instead and have better control. In the future we can add more beacon queue specific stuff there (maybe tweak beacon timers or something), for now just call ath5k_hw_stop_tx_dma. * Also since we don't call ath5k_hw_stop_rx/tx_dma from outside dma.c, make them static.

This feature is to mitigate the problem of certain 3 stream chips that exceed the PCIe power requirements.An EEPROM flag controls which chips have APM enabled which is basically read from miscellaneous configuration element of the EEPROM header. This workaround will reduce power consumption by using 2 Tx chains for Single and Double stream rates (5 GHz only).All self generated frames (regardless of rate) are sent on 2 chains when this feature is enabled(Chip Limitation).
