| * mac80211: Add support for connection quality monitoringJuuso Oikarinen2010-03-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for the set_cqm_config op. This op function configures the requested connection quality monitor rssi threshold and rssi hysteresis values to the hardware if the hardware supports IEEE80211_HW_SUPPORTS_CQM. For unsupported hardware, currently -EOPNOTSUPP is returned, so the mac80211 is currently not doing connection quality monitoring on the host. This could be added later, if needed.

| * cfg80211: Add connection quality monitoring support to nl80211Juuso Oikarinen2010-03-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for basic configuration of a connection quality monitoring to the nl80211 interface, and basic support for notifying about triggered monitoring events. Via this interface a user-space connection manager may configure and receive pre-warning events of deteriorating WLAN connection quality, and start preparing for roaming in advance, before the connection is already lost. An example usage of such a trigger is starting scanning for nearby AP's in an attempt to find one with better connection quality, and associate to it before the connection characteristics of the existing connection become too bad or the association is even lost, leading in a prolonged delay in connectivity. The interface currently supports only RSSI, but it could be later extended to include other parameters, such as signal-to-noise ratio, if need for that arises.

| * mac80211: Add support for connection monitor in hardwareJuuso Oikarinen2010-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is based on a RFC patch by Kalle Valo. The wl1271 has a feature which handles the connection monitor logic in hardware, basically sending periodically nullfunc frames and reporting to the host if AP is lost, after attempting to recover by sending probe-requests to the AP. Add support to mac80211 by adding a new flag IEEE80211_HW_CONNECTION_MONITOR which prevents conn_mon_timer from triggering during idle periods, and prevents sending probe-requests to the AP if beacon-loss is indicated by the hardware.

| * mac80211: give warning if building w/out rate ctrl algorithmAndres Salomon2010-03-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I discovered that if EMBEDDED=y, one can accidentally build a mac80211 stack and drivers w/ no rate control algorithm. For drivers like RTL8187 that don't supply their own RC algorithms, this will cause ieee80211_register_hw to fail (making the driver unusable). This will tell kconfig to provide a warning if no rate control algorithms have been selected. That'll at least warn the user; users that know that their drivers supply a rate control algorithm can safely ignore the warning, and those who don't know (or who expect to be using multiple drivers) can select a default RC algorithm.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Drivers can now advertise to cfg80211 that they have multiple MAC addresses reserved for a device, but we don't currently make use of that in mac80211.

| * mac80211: Improve software scan timingHelmut Schaa2010-03-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current software scan implemenation in mac80211 returns to the operating channel after each scanned channel. However, in some situations (e.g. no traffic) it would be nicer to scan a few channels in a row to speed up the scan itself. Hence, after scanning a channel, check if we have queued up any tx frames and return to the operating channel in that case. Unfortunately we don't know if the AP has buffered any frames for us. Hence, scan only as many channels in a row as the pm_qos latency and the negotiated listen interval allows us to. Signed-off-by: Helmut Schaa <helmut.schaa@googlemail.com> Signed-off-by: John W.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch reduces timer events while keeping accuracy by rounding our timer and/or batching several address validations in addrconf_verify(). addrconf_verify() is called at earliest timeout among interface addresses' timeouts, but at maximum ADDR_CHECK_FREQUENCY (120 secs). In most cases, all of timeouts of interface addresses are long enough (e.g. several hours or days vs 2 minutes), this timer is usually called every ADDR_CHECK_FREQUENCY, and it is okay to be lazy. (Note this timer could be eliminated if all code paths which modifies variables related to timeouts call us manually, but it is another story.) However, in other least but important cases, we try keeping accuracy. When the real interface address timeout is coming, and the timeout is just before the rounded timeout, we accept some error. When a timeout has been reached, we also try batching other several events in very near future. Signed-off-by: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org> Signed-off-by: David S.
