Change the way we alloc the transport on the way. Since the transport is allocated from a bus specific area, we can give the bus specific parameters (i.e. pci_dev for PCI) to the transport.

This cause by hyperv netvsc driver always copy the trailer padding to the data packet, and then the skb received from netdevice may include wrong skb->len (20 bytes larger than the real size normally).

2012-02-01iwlwifi: don't mess up QoS counters with non-QoS framesEmmanuel Grumbach
In my AMPDU rework, I rely on the sequence numbers of frames. But I didn't check that the frame has a valid tid before updating the tracking counters. As a result, the Tx queues were stalled. People who hit this bug saw that we simply didn't let any data out. This bug was introduced in 3.3. This patch fixes that and checks that the frame is a QoS frame before looking at its tid and changing the counters.

2012-02-01rt2800lib: fix wrong -128dBm when signal is stronger than -12dBmLuigi Tarenga
This patch correct the type of variables containing the rssi values read from the rxwi. In function rt2800_agc_to_rssi() 3 variables (rssi0, rssi1, rss2) defined as int was assigned a 16bit signed values as unsigned. From a test with a hi-gain antenna I verified that the rxwi contains signed rssi values in the range -13/+81 (inclusive) with 0 as an error condition. In case of negative values a condition is triggered and the function return -128dBm while the signal is at its maximum. This patch correct the cast so negative values are not treated as very high positive values (ex. -13 does not become 243).

The X520 family of network devices, with the 82599 chip, support a small number of Intel-verified SFP+ modules on their NICs. To maintain stability and quality, the current devices restrict untested 3rd party SFP+ modules. This patch introduces a module parameter for ixgbe to allow these untested modules at the user's peril. It also includes a warning to the syslog alerting users that the modules aren't supported, and results may vary.

Driver updates are therefore required to support other boards that also use the CS89x0.

2012-01-30rtlwifi: Convert to asynchronous firmware loadLarry Finger
This patch addresses a kernel bugzilla report and two recent mail threads. The kernel bugzilla report is https://bugzilla.kernel.org/show_bug.cgi?id=42632, which reports a udev timeout on boot. The first mail thread, which was on LKML (http://lkml.indiana.edu/hypermail/ linux/kernel/1112.3/00965.html) was for a WARNING that occurs after a suspend/resume cycle for rtl8192cu. The scond mail thread (http://marc.info/?l=linux-wireless&m=132655490826766&w=2) concerned changes in udev that break drivers that delay while firmware is loaded on modprobe. This patch converts all rtlwifi-based drivers to use the asynchronous firmware loading mechanism. Drivers rtl8192ce, rtl8192cu and rtl8192de share a common callback routine. Driver rtl8192se needs different handling of the firmware, thus it has its own code. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Cc: Stable <stable@vger.kernel.org> Signed-off-by: John W.

2012-01-30iwlwifi: always restrict scan dwell in P2PJohannes Berg
Whenever the PAN (P2P) context is active, it has timers in the uCode that prevent sleep, so scanning can't be out of channel for more than the beacon interval programmed into the device. Before this patch, a full scan including any passive channels when P2P was active would stall forever because it wouldn't find time to execute the passive requests (for default beacon intervals of 100 TU.)

2012-01-30iwlwifi: fix uCode event tracingJohannes Berg
Fix multiple bugs in event tracing: 1) If you enable uCode tracing with the device down, it will still attempt to access the device and continuously log "MAC is in deep sleep!" errors. Fix this by only starting logging when the device is actually alive. 2) Now you can set the flag when the device is down, but logging doesn't happen when you bring it up. To fix that, start logging when the device comes alive. This means we don't log before -- we could do that but I don't need it right now. 3) For some reason we read the error instead of the event log -- use the right pointer. 4) Optimise SRAM reading of event log header. 5) Fix reading write pointer == capacity, which can happen due to racy SRAM access 6) Most importantly: fix an error where we would try to read WAY too many events (like 2^32-300) when we read the wrap counter before it is updated by the uCode -- this does happen in practice and will cause the driver to hang the machine. 7) Finally, change the timer to 10ms instead of 100ms as 100ms is too slow to capture all data with a normal event log and with 100ms the log will wrap multiple times before we have a chance to read it.

2012-01-30ath6kl: Wait for host sleep mode cmd processed event during WOW suspendRaja Mani
For every WMI_SET_HOST_SLEEP_MODE_CMDID command (send from the host), the firmware sends WMI_SET_HOST_SLEEP_MODE_CMD_PROCESSED_EVENTID as an acknowledgement to the host. In order to being sync with the firmware, the host has to wait for WMI_SET_HOST_SLEEP_MODE_CMD_PROCESSED_EVENT event before going to the suspend state. This patch ensures ath6kl_wow_suspend() waits until it gets this event after sending set host sleep mode command. This patch adds, * New command WMI_SET_HOST_SLEEP_MODE_CMD_PROCESSED_EVENTID in WMI event table. * New WMI function ath6kl_wmi_host_sleep_mode_cmd_prcd_evt_rx() to process the event. * New flag HOST_SLEEP_MODE_CMD_PROCESSED in VIF flags to record the arrival of the event.
