2014-02-28wil6210: disconnect only requested peerVladimir Kondratiev
Disconnect event reported by the FW, should lead to disconnection of only requested peer. Find for the appropriate CID and disconnect only it For AP-like interface, notify cfg80211 with del_sta(), for the client type interface, disconnect and turn link off.

2014-02-28wil6210: Find free vring for TxVladimir Kondratiev
There are 24 possible Tx vrings; when doind multiple connections, more then one vring has to be used. Search for free one and select it. Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2014-02-28wil6210: Block ACKVladimir Kondratiev
When running multiple connections, hardware can't do BACK reordering and it should be done on the host. Model after mac80211's implementation. Drop RCU for now; to be re-added when BACK will be stabilized BACK handshaking is not implemented yet in the hardware, pretend it was done to support the way FW operating Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: John W.

2014-02-28wil6210: multiple connect - initial supportVladimir Kondratiev
Enable multiple (up to 8 - HW/FW limitation) simultaneous connections. Each connection has its own CID (connection ID) that describes chip's beam-forming entity. Tx Vring should refer to correct CID for frame to reach its destination. Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2013-11-15tree-wide: use reinit_completion instead of INIT_COMPLETIONWolfram Sang
Use this new function to make code more comprehensible, since we are reinitialzing the completion, not initializing.

2013-06-12wil6210: Fix AP/PCP start flowKirshenbaum Erez
WMI PCP Start flow should not be handled through: net_device_ops->ndo_open()->wil_up()->__wil_up() because it missing mandatory FW parameters (SSID,Channel,IEs, Security...). Prior to AP starting __wil_up() may be called with iftype set cfg80211_ops->change_virtual_intf(NL80211_IFTYPE_AP or STATION) depend on the application hostapd/wpa_supplicant/iw. there should not be an attempt to start an AP flow, AP/PCP start flow will be started latter by cfg80211_ops->start_ap().

2013-06-12wil6210: Init Rx vring right after resetVladimir Kondratiev
at the vring initialisation, memory pool get allocated in the FW. Make it 1-st because FW need this memory pool to precess next commands Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2013-05-22wil6210: use NAPIVladimir Kondratiev
Introduce NAPI for Rx and Tx completion. This fixes packet reordering that happens when Rx handled right in the IRQ: netif_rx puts packet in 'percpu' queue, then network stack fetches packets from 'percpu' queues for processing, with different pattern of queue switching. As result, network stack see packets in different order. This causes hard to understand TCP throughput degradation in about 30min Complete polling if only one packet was processed - this eliminates empty polls that would be otherwise done at the end of each burst Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2013-03-13wil6210: sync with new firmwareVladimir Kondratiev
Adjust driver for changes in the FW API. Noticeable changes in the FW are: - temperature sensing - infrastructure for multiple connections - infrastructure for P2P - signal strength indication This commit introduces only changes that are required to support same functionality as previous firmware, no new features.

2013-03-13wil6210: new SW resetVladimir Kondratiev
New firmware allows for shorter SW reset procedure. After SW reset, FW raises "fw done" IRQ, at this moment mailbox control structures are initialized, driver caches it. New status bit wil_status_reset_done introduced to track completion of the reset. It is set by "fw ready" irq, and required for WMI rx flow to access control structures. WMI Tx flow protected by other status bit, wil_status_fwready. It can't be set before wil_status_reset_done is set by design.

2013-01-30wil6210: Fix "don't scan after connect" logicVladimir Kondratiev
When connect times out, scan was not re-enabled. Strictly say, it is firmware issue - it should issue "disconnect" event but it does not. Compensate in the driver. Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2013-01-04wireless: add new wil6210 802.11ad 60GHz driverVladimir Kondratiev
This adds support for the 60 GHz 802.11ad Wilocity card through a new driver, wil6210. Wilocity implemented the firmware, QCA maintains the device driver. Currently supported: - STA: with security - AP: limited to 1 connected STA, security disabled - Monitor: due to a hardware/firmware limitation either control or non-control frames are monitored Using a STA and AP with this drive, one can assemble a fully functional BSS. Throughput of 1.2Gbps is achieved with iperf. The wil6210 cards have on-board flash memory for the firmware, the cards comes pre-flashed and no firmware download is required.
