* mwifiex: fix missing tsf_val TLVBing Zhao2011-05-022-2/+7
| | | | | | | | | | In mwifiex_cmd_append_tsf_tlv(), two tsf_val TLVs should be filled in the buffer and then sent to firmware. The missing first TLV for tsf_val is added back in this patch. Signed-off-by: Bing Zhao <bzhao@marvell.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* rt2x00: Add autowake support for USB hardwareIvo van Doorn2011-05-026-0/+139
| | | | | | | | | | | | | The USB drivers don't support automatically waking up when in powersaving mode, add a work object which will wakeup the device in time to receive the next beacon. Based on that beacon, we either go back into powersaving mode, or we remain awake to receive the buffered frames for our station. Some part of the code, especially rt2x00lib_find_ie and rt2x00lib_rxdone_check_ps are inspired on the code from carl9170. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

| | | | | | | | | | | | | | Add recycling functionality to rt2x00usb_register_read_async. When the callback function returns true, resubmit the urb to read the register again. This optimizes the rt2800usb driver when multiple TX status reports are pending in the register, because now we don't need to allocate the rt2x00_async_read_data and urb structure each time.

* iwlagn: prefer BSS contextJohannes Berg2011-04-301-0/+14
| | | | | | | | | | | | | | | If an interface type changes from a type that is only supported on the PAN context (e.g. P2P GO) to a type that is supported on the BSS context, and the BSS context is not in use, then we need to use the BSS context instead of changing the device type within the context. To achieve this, refuse the type change, which causes a down/up cycle that will allocate the BSS context for the interface.

| | | | | | | | | | | | | The current RXON checking doesn't verify that the channel is valid (or at least non-zero), so add that. Also, add a WARN() so we get a stacktrace, and capture a bitmask of errors in order to capture all necessary information in the warning itself (in case the previous messages are snipped off.)

* iwlagn: introduce silent grabbing of NIC accessJohannes Berg2011-04-302-5/+14
| | | | | | | | | | | | | | | There are a few cases like the WoWLAN support I'm writing that require attempting to access the NIC when it is known that it might not be accessible, e.g. after the system woke up and the platform might have reset the device. To avoid messages in this case, introduce the new function iwl_grab_nic_access_silent(), it will only return an error status.

* iwlagn: avoid hangs when restarting deviceJohannes Berg2011-04-303-6/+20
| | | | | | | | | | | | | | | | | | | If a device error happens while the uCode is being loaded or initialised, we will attempt to restart the device (which will likely fail again, but that's not the issue here). During this new restart, we turn off the device, but as the uCode failed to initialise it already is turned off. As a consequence, grabbing NIC access will fail and cause excessive messages and hangs. To fix this issue, introduce a new status bit and only attempt to reprogram the device when it isn't already disabled.

* mwl8k: Reducing extra_tx_headroom for tx optimization in AP modeYogesh Ashok Powar2011-04-291-5/+26
| | | | | | | | | | | | | | | | | | | | | | | The tx_headroom required for mwl8k driver is 32 bytes and it can use the space for 802.11 header received from mac80211. mwl8k considers the smallest 802.11 frame (CTS2self of 10 bytes) that can be received from mac80211 to compute the extra_tx_headroom as 22 (32 - 10) bytes. When the wireless interface is part of bridge, this extra_tx_headroom requirement results in a memcpy in mac80211 (in function pskb_expand_head) for all the data frames needing L2 forwarding/bridging, when NET_SKB_PAD is defined as 32. This patch reduces the extra_tx_headroom by 8 bytes so that memcpy of data frames in mac80211 is avoided in this case. The resize will be required in driver for frames with 802.11 header size of less than 18 bytes.

That changed default behaviour of driver. Previously we initialized device to transmit at maximum available power by default. Patch change again to previous behaviour and cleanup tx power initialization. Fortunately this is not critical fix, as mac80211 layer setup tx power lately to 14dB, hence device does not operate at minimal transmit power all the time.
