2012-04-17rt2x00: Don't let mac80211 send a BAR when an AMPDU subframe failsAndreas Hartmann
There are connection stalls or very poor throughputs with rt2800 hardware using 802.11n in AP mode since patch "mac80211: retry sending failed BAR frames later instead of tearing down aggr"[1][2]. Since rt2800 hardware is not able to correctly report the tx status of BAR frames, this patch removes as workaround the existing error handling on AP side, which lets mac80211 send a BAR when an AMPDU subframe fails. As a result, most wifi clients (aside from Intel STAs on Windows) instead will timeout now the reorder buffer and request the lost frame again. The correct solution would be, to tear down BA session on AP side. This patch was born on the basis of "[RFT] rt2x00: Tear down BA session on QoS frame failure"[3]. Thanks to Helmut Schaa for his support!

2012-04-16dummy: Add ndo_uninit().Hiroaki SHIMODA
In register_netdevice(), when ndo_init() is successful and later some error occurred, ndo_uninit() will be called. So dummy deivce is desirable to implement ndo_uninit() method to free percpu stats for this case. And, ndo_uninit() is also called along with dev->destructor() when device is unregistered, so in order to prevent dev->dstats from being freed twice, dev->destructor is modified to free_netdev().

2012-04-16iwlwifi: remove uCode alternatives mechanismJohannes Berg
We've never released firmware using the alternatives mechanism and our build process makes that difficult anyway. This means that in every file we have ever built (except maybe by hand for testing) the listed alternative was 0. Make the alternative field in the TLVs part of the TLV number (thus expanding that to 32 bits); this gives us more TLV numbers (not really needed) and more importantly protects against rogue firmware files that actually do use the alternatives mechanism -- those will now be rejected since they don't contain any valid TLVs.

2012-04-16iwlwifi: remove no_sleep_autoadjustJohannes Berg
My original idea with this was to adjust the sleep pattern of the uCode based on the maximum network latency userspace asked for. Due to nobody wanting to test it, this logic was disabled by default. It seems the time has come to remove it, since it's not only always disabled but there also don't seem to be any applications that actually request a max network latency.

If either call to pcan_usb_pro_send_req() in drivers/net/can/usb/peak_usb/pcan_usb_pro.c::pcan_usb_pro_init() fails, we'll leak the memory we allocated to 'usb_if' with kzalloc() when the 'usb_if' variable goes out of scope without having been assigned to anything as we 'return err;'.
