2015-10-26ath6kl: add missing of_node_putJulia Lawall
for_each_compatible_node performs an of_node_get on each iteration, so a break out of the loop requires an of_node_put. A simplified version of the semantic patch that fixes this problem is as follows (http://coccinelle.lip6.fr): // <smpl> @@ expression e; local idexpression n; @@ for_each_compatible_node(n,...) { ... when != of_node_put(n) when != e = n ( return n; | + of_node_put(n); ? return ...; ) ... } // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: David S.

2015-09-26ath10k: fix DMA related firmware crashes on multiple devicesFelix Fietkau
Some platforms really don't like DMA bursts of 256 bytes, and this causes the firmware to crash when sending beacons. Also, changing this based on the firmware version does not seem to make much sense, so use 128 bytes for all versions.

ath9k inserts padding between the 802.11 header and the data area (to align it).

Pull networking updates from David Miller: "Another merge window, another set of networking changes. I've heard rumblings that the lightweight tunnels infrastructure has been voted networking change of the year. But what do I know? 1) Add conntrack support to openvswitch, from Joe Stringer. 2) Initial support for VRF (Virtual Routing and Forwarding), which allows the segmentation of routing paths without using multiple devices. There are some semantic kinks to work out still, but this is a reasonably strong foundation. From David Ahern. 3) Remove spinlock fro act_bpf fast path, from Alexei Starovoitov. 4) Ignore route nexthops with a link down state in ipv6, just like ipv4.

2015-08-26ath10k: add qca6164 supportMichal Kazior
This adds additional 0x0041 PCI Device ID definition to ath10k for QCA6164 which is a 1 spatial stream sibling of the QCA6174 (which is 2 spatial stream chip). The QCA6164 needs a dedicated board.bin file which is different than the one used for QCA6174. If the board.bin is wrong the device will crash early while trying to boot firmware. The register dump will look like this: ath10k_pci 0000:02:00.0: firmware register dump: ath10k_pci 0000:02:00.0: [00]: 0x05010000 0x000015B3 0x000A012D 0x00955B31 ... Note the value 0x000A012D.

2015-08-26ath10k: add spectral scan support for 10.4 fwRaja Mani
To enable/configure spectral scan parameters in 10.4 firmware, existing wmi spectral related functions can be reused. Link those functions in 10.4 wmi ops table. In addition, adjust bin size (only when size is 68 bytes) before reporting bin samples to user space. The background for this adjustment is that qca99x0 reports bin size as 68 bytes (64 bytes + 4 bytes) in report mode 2. First 64 bytes carries in-band tones (-32 to +31) and last 4 byte carries band edge detection data (+32) mainly used in radar detection purpose. Additional last 4 bytes are stripped to make bin size valid one. This bin size adjustment will happen only for qca99x0, all other chipsets will report proper bin sizes (64/128) without extra 4 bytes being added at the end. The changes are validated in qca99x0 using 10.4 firmware. Signed-off-by: Raja Mani <rmani@qti.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

2015-08-17ath10k: refactor phyerr event handlersRaja Mani
Existing phyerr event handlers directly uses phyerr header format (ie, struct wmi_phyerr and struct wmi_phyerr_event) in the code exactly on how firmware packs it. This is the problem in 10.4 fw specific phyerr event handling where it uses different phyerror header format. Before adding 10.4 specific handler, little bit of refactor is done in existing phyerr handlers. Two new abstracted structures (struct wmi_phyerr_ev_hdr_arg and struct wmi_phyerr_ev_arg) are introduced to remove dependency of using firmware specific header format in the code. So that firmware specific phyerror handlers can populate values to abstracted structures and the following code can use abstracted struct for further operation. .pull_phyerr_hdr is added newly to pull common phyerr header info like tsf, buf_len, number of phyerr packed. Existing .pull_phyerr handler is changed and called to parse every sub phyerrs in the event. Validated these refactoring on qca988x hw2.0 using fw 10.2.4 version.

Since there is a new state before the completion, the handler is to fixed so that the counts are deducted from the ones reported with CHAN_INFO_START rather than the ones reported with CHAN_INFO_PRE_COMPLETE.

2015-08-17ath10k: wake up queue upon vif creationMichal Kazior
Vif's vdev_id is used as queue number. However due to the tx pausing design in ath10k it was possible for a new interface to be created with its tx queue stopped (via ieee80211_stop_queues). This could in turn leave the interface inoperable until ath10k_mac_tx_unlock() was called. This problem only affected multi-vif scenarios when new interfaces were created some time later after other interfaces have been running for some time and had Tx queue full at some point prior. Possible manifestation of the bug was authentication timeout for a client vif.

2015-08-13ath10k: remove futile fragmentation threshold configMichal Kazior
Commit 1010ba4c5d1c ("ath10k: unregister and remove frag_threshold callback") didn't remove all instances of (futile) fragmentation threshold configuration. No known firmware supports the parameter so don't even bother setting it. Signed-off-by: Michal Kazior <michal.kazior@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
