ath10k: fix invalid NSS for 4x4 devices

2015-12-09T19:34:33+00:00

commit f680f70adbeab28b35f849016b964dd645db6237 upstream. The number of spatial streams that are derived from chain mask for 4x4 devices is using wrong bitmask and conditional check. This is affecting downlink throughput for QCA99x0 devices. Earlier cfg_tx_chainmask is not filled by default until user configured it and so get_nss_from_chainmask never be called. This issue is exposed by recent commit 166de3f1895d ("ath10k: remove supported chain mask"). By default maximum supported chain mask is filled in cfg_tx_chainmask.

ath10k: use station's current operating mode from assoc request

2015-12-09T19:34:33+00:00

commit 72f8cef5d1155209561b01e092ce1a04ad50c4cb upstream. The current number of spatial streams used by the client is advertised as a separate IE in assoc request. Use this information to set the NSS operating mode. Fixes: 45c9abc059fa ("ath10k: implement more versatile set_bitrate_mask").

ath10k: add ATH10K_FW_FEATURE_RAW_MODE_SUPPORT to ath10k_core_fw_feature_str[]

2015-12-09T19:34:33+00:00

commit 5af82fa66a7ee8dfc29fadb487a02e2ef14ea965 upstream. This was missed in the original commit adding the flag and ath10k only printed "bit10": ath10k_pci 0000:02:00.0: qca988x hw2.0 (0x4100016c, 0x043202ff) fw 10.2.4.70.6-2 api 3 htt-ver 2.1 wmi-op 5 htt-op 2 cal otp max-sta 128 raw 0 hwcrypto 1 features no-p2p,bit10 Also add a build test to avoid this happening again.

ath6kl: add missing of_node_put

2015-10-27T05:08:12+00:00

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): // @@ 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 ...; ) ... } // Signed-off-by: Julia Lawall Signed-off-by: David S.

ath10k: fix DMA related firmware crashes on multiple devices

2015-09-26T17:48:25+00:00

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: declare required extra tx headroom

2015-09-26T17:34:38+00:00

ath9k inserts padding between the 802.11 header and the data area (to align it). Since it didn't declare this extra required headroom, this led to some nasty issues like randomly dropped packets in some setups. Cc: stable@vger.kernel.org Signed-off-by: Felix Fietkau Signed-off-by: Kalle Valo

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. From Andy Gospodarek. 5) Remove spinlock from fast path of act_gact and act_mirred, from Eric Dumazet. 6) Document the DSA layer, from Florian Fainelli. 7) Add netconsole support to bcmgenet, systemport, and DSA. Also from Florian Fainelli. 8) Add Mellanox Switch Driver and core infrastructure, from Jiri Pirko. 9) Add support for "light weight tunnels", which allow for encapsulation and decapsulation without bearing the overhead of a full blown netdevice. From Thomas Graf, Jiri Benc, and a cast of others. 10) Add Identifier Locator Addressing support for ipv6, from Tom Herbert. 11) Support fragmented SKBs in iwlwifi, from Johannes Berg. 12) Allow perf PMUs to be accessed from eBPF programs, from Kaixu Xia. 13) Add BQL support to 3c59x driver, from Loganaden Velvindron. 14) Stop using a zero TX queue length to mean that a device shouldn't have a qdisc attached, use an explicit flag instead. From Phil Sutter. 15) Use generic geneve netdevice infrastructure in openvswitch, from Pravin B Shelar. 16) Add infrastructure to avoid re-forwarding a packet in software that was already forwarded by a hardware switch. From Scott Feldman. 17) Allow AF_PACKET fanout function to be implemented in a bpf program, from Willem de Bruijn" * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1458 commits) netfilter: nf_conntrack: make nf_ct_zone_dflt built-in netfilter: nf_dup{4, 6}: fix build error when nf_conntrack disabled net: fec: clear receive interrupts before processing a packet ipv6: fix exthdrs offload registration in out_rt path xen-netback: add support for multicast control bgmac: Update fixed_phy_register() sock, diag: fix panic in sock_diag_put_filterinfo flow_dissector: Use 'const' where possible. flow_dissector: Fix function argument ordering dependency ixgbe: Resolve "initialized field overwritten" warnings ixgbe: Remove bimodal SR-IOV disabling ixgbe: Add support for reporting 2.5G link speed ixgbe: fix bounds checking in ixgbe_setup_tc for 82598 ixgbe: support for ethtool set_rxfh ixgbe: Avoid needless PHY access on copper phys ixgbe: cleanup to use cached mask value ixgbe: Remove second instance of lan_id variable ixgbe: use kzalloc for allocating one thing flow: Move __get_hash_from_flowi{4,6} into flow_dissector.c ixgbe: Remove unused PCI bus types ...

ath10k: fix compilation warnings in wmi phyerr pull function

2015-08-26T09:33:52+00:00

Below compilation warnings are observed in gcc version 4.8.2. Even though it's not seen in bit older gcc versions (for ex, 4.7.3), It's good to fix it by changing format specifier from %d to %zd in wmi pull phyerr functions. wmi.c: In function 'ath10k_wmi_op_pull_phyerr_ev': wmi.c:3567:8: warning: format '%d' expects argument of type 'int', but argument 4 has type 'long unsigned int' [-Wformat=] left_len, sizeof(*phyerr)); ^ wmi.c: In function 'ath10k_wmi_10_4_op_pull_phyerr_ev': wmi.c:3612:8: warning: format '%d' expects argument of type 'int', but argument 4 has type 'long unsigned int' [-Wformat=] left_len, sizeof(*phyerr)); ^ Fixes: 991adf71a6cd ("ath10k: refactor phyerr event handlers") Fixes: 2b0a2e0d7c2f ("ath10k: handle 10.4 firmware phyerr event") Signed-off-by: Raja Mani Signed-off-by: Kalle Valo
