2009-12-22libertas: remove priv->capabilityHolger Schurig
This variable was once set to WLAN_CAPABILITY_SHORT_PREAMBLE and there's no code that could change the variable to something else. Therefore it seems this is not necessary :-) Signed-off-by: Holger Schurig <holgerschurig@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2009-12-22libertas: remove mesh_autostart_enabled and sync_channelHolger Schurig
mesh_autostart_enabled was nowhere set. Rumor is that this is used in the OLPC tree, but they never did submit their code upstream. After removing this code, it turned out that the sync_channel stuff is now also unused, so get rid of that as well. Signed-off-by: Holger Schurig <holgerschurig@gmail.com> Signed-off-by: John W.

2009-12-22libertas: use priv->mesh_tlv instead of priv->mesh_fw_verHolger Schurig
Both variables contained the same information (no mesh, old mesh, new mesh). So we can get rid of one variable. Also move the mesh-version test from cmd.c into mesh.c. Signed-off-by: Holger Schurig <holgerschurig@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2009-12-22mac80211: enable spatial multiplexing powersaveJohannes Berg
Enable spatial multiplexing in mac80211 by telling the driver what to do and, where necessary, sending action frames to the AP to update the requested SMPS mode. Also includes a trivial implementation for hwsim that just logs the requested mode. For now, the userspace interface is in debugfs only, and let you toggle the requested mode at any time.

2009-12-21rt2x00: Fix trimming of L2 padded frames.Gertjan van Wingerde
Ensure that frames without payload are properly trimmed in rt2x00queue_insert_l2pad.

2009-12-21rt2x00: Fix rt2800usb RX frame format and as such L2PADBenoit Papillault
According to Ralink source code, the RX frame format is RXINFO + RXWI + 802.11 frame + RXD, including various padding. Before this patch, we were using RXD + RXWI + 802.11 frame, so RXD was not correct. Doing this, we fix the L2PAD bit which is now correctly set on received frames.

2009-12-21rt2x00: Disable RX aggregation for rt2800usbBenoit PAPILLAULT
RX aggregation is a way to receive multiple 802.11 frames in one RX buffer. However, we don't know yet how to handle this case in rt2800usb_fill_rxdone and this has probably no impact on RX performance as well, so we disable it Signed-off-by: Benoit Papillault <benoit.papillault@free.fr> Acked-by: Gertjan van Wingerde <gwingerde@gmail.com> Acked-by: Ivo van Doorn <ivdoorn@gmail.com> Signed-off-by: John W.

2009-12-21rt2x00: Reorganize L2 padding inserting function.Gertjan van Wingerde
Simplify the rt2x00queue_insert_l2pad function by handling the alignment operations one by one. Do not special case special circumstances. Basically first perform header alignment, and then perform payload alignment (if any payload does exist). This results in a properly aligned skb. The end result is better readable code, with better results, as now L2 padding is inserted only when a payload is actually present in the frame.

2009-12-21rt2x00: Remove SKBDESC_L2_PADDED flag.Gertjan van Wingerde
With the improved L2 padding code, this flag is no longer necessary, as the rt2x00queue_remove_l2pad is capable of detecting by itself if L2 padding is applied.

2009-12-21rt2x00 : trim the skb after having the l2pad removed.Alban Browaeys
Otherwise we end up truncating the skb before removing the l2pad thus we might have the truncated part become garbage while getting it back in remove_l2pad.

2009-12-21iwlwifi: remove extra error msg on sensitivity calibrationWey-Yi Guy
Do not need to log error when fail the sensitivity command, driver will send sensitivity write command to uCode after each sensitivity calibration if station is associated with AP. It is a normal case when user unload the module or shutdown the system while still associated with the AP, since uCode already on the way down, it will not reply the sensitivity write request; report error in this case will give misleading information, remove the error checking here to provide a clean shutdown if no other error detected.

2009-12-21iwlwifi: add continuous uCode event log capabilityWey-Yi Guy
In order to help uCode debugging, adding the capability to provide continuous uCode event logging function. uCode events is located in round-robin event queue and filled by uCode, by enable continuous event logging, driver check the write pointer and log the newly added events in iwl_bg_ucode_trace() timer function. There is still possibility of missing events if event queue being wrapped before next event dump; but with this capability, we can have much better understanding of the uCode behavior during runtime; it can help to debug the uCode related issues. Methods to enable/disable the continuous event log: step 1: enable ucode trace timer "echo 1 > /sys/kernel/debug/ieee80211/phyX/iwlagn/debug/ucode_tracing" step 2: start ftrace sudo ./trace-cmd record -e iwlwifi_ucode:* sleep 1d step 3: stop ftrace sudo ./trace-cmd report trace.dat step 4: disable ucode trace timer "echo 0 > /sys/kernel/debug/ieee80211/phyX/iwlagn/debug/ucode_tracing" use "ucode_tracing" debugfs file to display number of event queue wrapped when driver attempt the continuous event logging. If event queue being wrapped more than once when driver has opportunity to log the event; it indicated there are events missing in the event log trace. This continuous event log function only available for 4965 and newer NICs.

2009-12-21wireless: hostap, fix oops due to early probing interruptColin Ian King
BugLink: https://bugs.launchpad.net/ubuntu/+bug/254837 Spurious shared interrupts or early probing interrupts can cause the hostap interrupt handler to oops before the driver has fully configured the IO base port addresses. In some cases the oops can be because the hardware shares an interrupt line, on other cases it is due to a race condition between probing for the hardware and configuring the IO base port. The latter occurs because the probing is required to determin the hardware port address which is only determined when the probe can interrupt the hardware (catch 22). This patch catches this pre-configured condition to avoid the oops.
