linux-stable.git/drivers/net/wireless, branch v3.2.39 Linux kernel stable tree rt2800usb: Add support for 2001:3c1e (D-Link DWA-125 rev B1) USB Wi-Fi adapter 2013-02-20T03:15:27+00:00 Maia Kozheva sikon@ubuntu.com 2012-12-09T09:07:40+00:00 31317e96c36a1d45bf6618a8f02839c924d2bcaf commit fd7b9270120ca7e53fbf0469febe0c68acf6a0a2 upstream. D-Link DWA-125/B1 is a relatively new USB Wi-Fi adapter, using a Ralink chipset supported by the rt2800usb driver. Currently, to work around the problem (it's missing in all present kernel versions, up to and including 3.7.x), I had to add this to /etc/rc.local: echo 2001 3c1e >> /sys/bus/usb/drivers/rt2800usb/new_id After that, the device works without problems. Been using it for over a week with no bugs in sight. The attached patch is trivial and simply adds the new USB ID to the list of devices handled by rt2800usb.

commit fd7b9270120ca7e53fbf0469febe0c68acf6a0a2 upstream.

D-Link DWA-125/B1 is a relatively new USB Wi-Fi adapter, using a
Ralink chipset supported by the rt2800usb driver. Currently, to work
around the problem (it's missing in all present kernel versions,
up to and including 3.7.x), I had to add this to /etc/rc.local:

echo 2001 3c1e >> /sys/bus/usb/drivers/rt2800usb/new_id

After that, the device works without problems. Been using it for over
a week with no bugs in sight.

The attached patch is trivial and simply adds the new USB ID to the
list of devices handled by rt2800usb.

mwifiex: fix incomplete scan in case of IE parsing error 2013-02-20T03:15:21+00:00 Bing Zhao bzhao@marvell.com 2013-01-29T22:38:02+00:00 c0e2ce8b690f9af541f1bc29e431185723bcc963 commit 8a7d7cbf7b5ff9912ef50b3e94c9ad9f37b1c75f upstream. A scan request is split into multiple scan commands queued in scan_pending_q. Each scan command will be sent to firmware and its response is handlded one after another. If any error is detected while parsing IE in command response buffer the remaining data will be ignored and error is returned. We should check if there is any more scan commands pending in the queue before returning error. This ensures that we will call cfg80211_scan_done if this is the last scan command, or send next scan command in scan_pending_q to firmware.
