* NFC: SHDLC implementationEric Lapuyade2012-04-124-0/+1058
| | | | | | | | | | | Most NFC HCI chipsets actually use a simplified HDLC link layer to carry HCI payloads. This implementation registers itself as an HCI device on behalf of the NFC driver.

* NFC: HCI supportEric Lapuyade2012-04-1210-0/+1695
| | | | | | | | | | This is an implementation of ETSI TS 102 622 specification. Many NFC chipsets use HCI as the host <-> target protocol on top of a serial link like i2c.

* NFC: Export target lost functionEric Lapuyade2012-04-122-0/+40
| | | | | | | | | | NFC drivers will call this routine when they detect that a tag leaves the RF field. This will eventually lead to the corresponding netlink event to be sent.

* iwlwifi: move eeprom into privJohannes Berg2012-04-1213-172/+155
| | | | | | | | | | | | | | | | | | | | | | The whole code around eeprom is distributed across whole bunch of different files, most of which belong to the to-be-DVM code. As a result, it is currently very hard to split out the EEPROM code to be generic. However, it is also quite unlikely that the current EEPROM code will be needed by the MVM code as that has different mechanisms to query the EEPROM (it does so through the uCode.) So, at least temporarily, move everything into priv. If it becomes necessary to use the code from MVM, we will have to split it out, but then it's also easier since we'll know what pieces we need.

| | | | | | | | | | | | | | | | | | Split the force_reset debugfs file into two different files: * "rf_reset" triggers a reset of the RF when written to and exposes statistics on RF resets when read * fw_restart triggers a firmware restart when written to and lives in the transport This cleans up all sources of firmware restart to originate within the transport layer and allows us to simplify some code.

* iwlwifi: move hw_params into privJohannes Berg2012-04-1217-169/+168
| | | | | | | | | | | | | The hw_params are mostly values that are derived from the actual hardware config.

* iwlwifi: move queue watchdog into transportJohannes Berg2012-04-1211-141/+91
| | | | | | | | | | | | | | | | | | | | | | | This removes one of the two sources of device restarts in the upper layer -- those are a bit inconvenient because normal restarts originate in the transport. By moving the watchdog down it can be treated the same. Also rewrite the watchdog logic. Timers are much more efficient when they never fire, so instead firing a timer every 500ms set up a timer for each TX queue and fire it only when the queue is really stuck. This avoids the CPU waking up when everything is working well. While at it, remove the wd_disable config item and replace it by simply setting wd_timeout to IWL_WATCHHDOG_DISABLED (0).

| | | | | | | | | | | | | | That way it isn't needed in hw_params, which is shared data. It also isn't really what we should configure in the transport, that is better just 4k/8k, so configure a bool and derive the page order in the transport. This also means the transport doesn't need access to the module parameter any more.

So we clean all this up and in doing so enable cut-specific code paths for cuts C and D, which would not have been executed because the CHIP_92D_{C,D}_CUT constants were wrong and the cut version was thus recorded incorrectly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | RSN capability field of RSN IE which is generated (which is what really advertised in beacon/probe response) differs from the one generated in wpa_supplicant. This inconsistency in rsn IE results in 4-way handshake failure. To fix this, configure rsn capability used in wpa_supplicant in firmware using a new wmi command, WMI_SET_IE_CMDID.

| * ath6kl: Store scan request info in-advance before sending SCAN requestRaja Mani2012-03-281-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In current code, Scan request info is recorded in vif->scan_req after sending SCAN request to the firmware in ath6kl_cfg80211_scan(). In some corner cases, firmware sends SCAN_COMPLETE event immediately when it receives SCAN request, which internally executes scan complete event handler ath6kl_cfg80211_scan_complete_event() first. So, Scan completion handler will a get a chance to executed even before storing scan request info in ath6kl_cfg80211_scan(). Scan completion handler never report SCAN_COMPLETE event to cfg80211 if scan request info(vif->scan_req) is NULL. This leads to scan failure issue ("Device or resource busy error") during next SCAN request from the user space. This patch ensures that scan request info is stored before sending SCAN request.
