* ath6kl: remove incorrect reset_resume handlerAlexey Khoroshilov2014-11-041-9/+0
| | | | | | | | | | | | | | Existing implementation of reset_resume handler just calls ath6kl_usb_remove() that deallocates all resources. It can lead to double free, etc. on disconnect. The patch removes reset_resume handler, so usb core could conservatively reset the driver. Found by Linux Driver Verification project (linuxtesting.org).

* ath6kl: convert a driver to use module_usb_driver()Himangi Saraogi2014-08-041-20/+1
| | | | | | | | | | This converts a driver in drivers/net/* to use the module_usb_driver() macro which makes the code smaller and a bit simpler. Signed-off-by: Himangi Saraogi <himangi774@gmail.com> Acked-by: Julia Lawall <julia.lawall@lip6.fr> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
* ath6kl: add support for ar6004 hw3.0Jessica Wu2014-07-141-0/+1
| | | | | | | | This change enables ath6kl driver to support ar6004 hw3.0. At the same time do some fixes in firmware initialisation which applies to ar6004 hw1.3 as well. Signed-off-by: Jessica Wu <wjessica@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
* ath6kl: convert ar6004 hardware flags to firmware feature flagsKalle Valo2014-07-141-2/+4
| | | | | | | | | | | | | The functionality defined through these flags were actually firmware features which can change between firmware versions. To make it possible to support different firmware versions with the same driver, convert the flags to firmware feature flags. For backwards compatibility support for old ar6004 firmware FW API 3 or smaller images we forcefully set the feature bits in the driver. Starting from FW API 5 the firmware image needs to set them.

From Stephen Hemminger and Paul Gortmaker. 3) A bug fix for UDP hash table allocation got lost in the pile due to one of those "you got it.. no I've got it.." situations. :-) From Tim Bird. 4) SKB coalescing in TCP needs to have stricter checks, otherwise we'll try to coalesce overlapping frags and crash. Fix from Eric Dumazet. 5) RCU routing table lookups can race with free_fib_info(), causing crashes when we deref the device pointers in the route. Fix by releasing the net device in the RCU callback.

| * USB: Disable hub-initiated LPM for comms devices.Sarah Sharp2012-05-181-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hub-initiated LPM is not good for USB communications devices. Comms devices should be able to tell when their link can go into a lower power state, because they know when an incoming transmission is finished. Ideally, these devices would slam their links into a lower power state, using the device-initiated LPM, after finishing the last packet of their data transfer. If we enable the idle timeouts for the parent hubs to enable hub-initiated LPM, we will get a lot of useless LPM packets on the bus as the devices reject LPM transitions when they're in the middle of receiving data. Worse, some devices might blindly accept the hub-initiated LPM and power down their radios while they're in the middle of receiving a transmission. The Intel Windows folks are disabling hub-initiated LPM for all USB communications devices under a xHCI USB 3.0 host. In order to keep the Linux behavior as close as possible to Windows, we need to do the same in Linux. Set the disable_hub_initiated_lpm flag for for all USB communications drivers. I know there aren't currently any USB 3.0 devices that implement these class specifications, but we should be ready if they do.

* ath6kl: add back beginnings of USB supportKalle Valo2012-01-181-0/+431
John Linville had to revert the part of USB support which was already in ath6kl due to build problems in commit cb00ec382b ("ath6kl: revert USB support"). Now that I fixed the build problems properly by adding ath6kl_core.ko kernel module it's possible to add back the (incomplete) USB support. This patch is a revert of John's patch and adds back the USB code which as already in ath6kl, only difference being minor changes in Makefile and adapting usb.c to new core function names. Note that USB support in ath6kl is not complete yet. This code only makes it possible to boot firmware but as HTC layer does not yet support USB it's not possible to send any WMI commands nor data packets to the firmware. That will be added soon.
