2015-08-13orinoco: Do not call wiphy_unregister() from free_orinocodev()Jes Sorensen
alloc_orinocodev() would allocate the wiphy entry, but it would only get registered much later in orinoco_init(). If something failed in the init process inbetween the call to alloc_orinocodev() and the completion of orinoco_init(), the drivers would end up calling wiphy_unregister() with a NULL pointer causing beautiful OOPS fireworks. Explicitly call wiphy_unregister() instead in the right places. Signed-off-by: Jes Sorensen <Jes.Sorensen@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2015-08-13mwifiex: claim sdio bus while downloading the firmwareAniket Nagarnaik
Our 8887 A2 chip can have separate firmware images for bluetooth and WLAN. We observed an issue during parallel downloading of these images by btmrvl and mwifiex drivers. This patch claims sdio bus before starting of the firmware download in mwifiex and releases it after completion to fix the problem.

In this driver, two variables are masked by one quantity, and then tested against a second number with more bits that the mask. Accordingly, the test always fails. To minimize the possibility of such typos, a symbolic definition of the mask is created and used. The separate load and mask operations are also combined into a single statement.

If peer creation failed during offchannel Tx the driver attempted to delete the peer nonetheless. This caused the ar->num_peers counter to be incorrectly decremented.

2015-08-13ath10k: reject 11b tx fragmentation configurationMichal Kazior
Even though there's a WMI enum for fragmentation threshold no known firmware actually implements it. Moreover it is not possible to rely frame fragmentation to mac80211 because firmware clears the "more fragments" bit in frame control making it impossible for remote devices to reassemble frames. Hence implement a dummy callback just to say fragmentation isn't supported. This effectively prevents mac80211 from doing frame fragmentation in software. This fixes Tx becoming broken after setting fragmentation threshold.

2015-08-10bcma: fix access to host_pdev for PCIe devicesHauke Mehrtens
bus->host_pdev is part of a union so bus->host_pdev != NULL is probably also true for PCIe devices, because there it accesses bus->host_pci. If we access the dev member at the offset defined in struct platform_device in struct pci_dev instead we probably get something else. This patch adds a new function which returns the host dev struct and NULL if we do not have a host dev. When this gets registered on MIPS brcm47xx we do not have a host dev in some situations. This function could also be used in other places. This problem was introduced in this commit: commit cae761b5a6bdc597ba476a040fdcd5b4bc559b85 Author: Rafa?

2015-08-10mt7601u: fix tx status reporting contextsJakub Kicinski

Since rx path is run in driver tasklet, tx status cannot be reported directly from interrupt context (there would be no way to lock it out). Add tasklet for tx and move all possible code from irq handler there. Note: tx tasklet is needed because workqueue is queued very rarely and that kills TCP performance.

2015-08-10wlcore: add p2p device supportEliad Peller
When starting a p2p mgmt interface, enable its device role. This allows us to keep the sta role disabled and scan on the dev role. In general, p2p management interfaces cannot send vif-specific commands to FW, as the vif role id is invalid. Only off-channel data and scans happen on this vif, so most ops are not relevant. If the vif is a p2p mgmt vif, block some mac80211 ops. Configure rate policies for p2p mgmt interface, as otherwise p2p packets come out with arbitrary rates. Since wpa_supplicant currently doesn't support standalone p2p device mode (without another attached managed interface), add p2p device to the allowed interface combinations without decreasing the allowed station count. Moreover, increase the station count in some cases, as AP mode usually starts as station interface, and the AP interface is now different from the p2p management one).
