cfg80211/mac80211: move wext SIWMLME into cfg80211 · 691597cb

由 Johannes Berg 提交于 4月 19, 2009

Since we have ->deauth and ->disassoc we can support the
wext SIWMLME call directly without driver wext handlers.

rtl8187: Implement TX/RX blink for LED · a027087a

由 Larry Finger 提交于 4月 16, 2009

The following patch implements some control over the LED on RTL8187B and
RTL8187L devices. Triggers are registered for TX and RX. Whenever the
trigger event occurs, the LED is turned off for 1/20 second, then turned
back on.

Note: For those RTL8187X devices that are built into the computer and have
a LED that is expected to be controlled with a radio switch, this patch will
not operate that LED. That will take a separate patch to be prepared later.

mac80211: Allow scan to be requested in AP mode · 357303e2

由 Jouni Malinen 提交于 4月 16, 2009

We can allow scan requests in AP mode as long as the interface has not
yet been configured to send out Beacon frames (or if beaconing has
been disabled prior to the scan request). This makes it easier to scan
for neighboring BSSes during AP initialization and makes it possible
to run a scan without setting the interface down, if needed. Without
this change, the only available option would be to set the interface
down, move into station mode, and set the interface up, prior to
requesting the scan.

mac80211: enable PS by default · bbbdff9e

由 Johannes Berg 提交于 4月 16, 2009

Enable PS by default (depending on Kconfig) -- rely on drivers
to control the level using pm_qos. Due to the previous patch
we turn off PS when necessary due to latency requirements.

This has a Kconfig symbol so people can, if they really want,
configure the default in their kernels. We may want to keep it
at "default y" only in wireless-testing for a while.

mac80211: implement beacon filtering in software · d91f36db

由 Johannes Berg 提交于 4月 16, 2009

Regardless of whether the hardware implements beacon filtering,
there's no need to process all beacons in software all the time
throughout the stack (mac80211 does a lot, then cfg80211, then
in the future possibly userspace).

This patch implements the "best possible" beacon filtering in
mac80211. "Best possible" means that it can look for changes in
all requested information elements, and distinguish vendor IEs
by their OUI.

In the future, we will add nl80211 API for userspace to request
information elements and vendor IE OUIs to watch -- drivers can
then implement the best they can do while software implements
it fully.

It is unclear whether or not this actually saves CPU time, but
the data is all in the cache already so it should be fairly
cheap. The additional _testing_, however, has great benefit;
Without this, and on hardware that doesn't implement beacon
filtering, wrong assumptions about, for example, scan result
updates could quickly creep into code.

mac80211: disable powersave if pm_qos asks for low latency · 10f644a4

When an application asks for a latency lower than the beacon interval
there's nothing we can do -- we need to stay awake and not have the
AP buffer frames for us. Add code to automatically calculate this
constraint in mac80211 so drivers need not concern themselves with it.

mac80211: improve powersave implementation · 965bedad

由 Johannes Berg 提交于 4月 16, 2009

When you have multiple virtual interfaces the current
implementation requires setting them up properly from
userspace, which is undesirable when we want to default
to power save mode. Keep track of powersave requested
from userspace per managed mode interface, and only
enable powersave globally when exactly one managed mode
interface is active and has powersave turned on.

Second, only start the dynPS timer when PS is turned
on, and properly turn it off when PS is turned off.

Third, fix the scan_sdata abuse in the dynps code.

Finally, also reorder the code and refactor the code
that enables PS or the dynps timer instead of having
it copied in two places.

atheros: fix propagation of bad EEPROM on regulatory init · 85efc86e

由 Luis R. Rodriguez 提交于 4月 13, 2009

When the EEPROM is not in good condition we cannot continue so
we currently bail out but only ath5k is bailing out properly.
Both ath9k and ar9170 were proceeding and if a user were to run
into this they'd see an obscure panic. Lets propagate the error
as intended and make sure we inform the user by lifting the
error message from debug to a kernel error.
