libertas: Update 11d info only when interface is active

2012-07-17T19:11:36+00:00

reg_notifier can be called before the interface is up.
Handle this correctly by storing the requested country code, then
apply the relevant configuration when the interface is brought up.

cfg80211: clarify set_channel APIs

2012-06-06T19:18:17+00:00

Now that we've removed all uses of the set_channel
API except for the monitor channel and in libertas,
clarify this. Split the libertas mesh use into a
new libertas_set_mesh_channel() operation, just to
keep backward compatibility, and rename the normal
set_channel() to set_monitor_channel().

Also describe the desired set_monitor_channel()
semantics more clearly.

libertas: add asynchronous firmware loading capability

2012-04-17T18:57:14+00:00

As described at
http://article.gmane.org/gmane.linux.kernel.wireless.general/86084
libertas is taking a long time to load because it loads firmware
during module loading.

Add a new API for interface drivers to load their firmware
asynchronously. The same semantics of the firmware table are followed
like before.

Interface drivers will be converted in follow-up patches, then we can
remove the old, synchronous firmware loading function.

libertas: detect TX lockups and reset hardware

2011-10-03T19:22:41+00:00

Recent patches added support for resetting the SD8686 hardware when
commands time out, which seems to happen quite frequently soon after
resuming the system from a Wake-on-WLAN-triggered resume.

At http://dev.laptop.org/ticket/10969 we see the same thing happen
with transmits. In this case, the hardware will fail to respond to
a frame passed for transmission, and libertas (correctly) will block
all further commands and transmissions as the hardware can only
deal with one thing at a time. This results in a lockup while the
system waits indefinitely for the dead card to respond.

Hook up a TX lockup timer to detect this and reset the hardware.

libertas: scan behaviour consistency improvements

2011-09-27T18:34:01+00:00

When scanning for the broadcast SSID, there is no need to add the
SSID TLV (restoring the behaviour of the driver behaviour in the wext
days, confirmed in Marvell specifications).

If bssid is unspecified, the current scan code will usually fire off an
active scan probing for the specific requested SSID. However, if a scan
is ongoing (or has just finished), those scan results will be used
instead (even if that scan is totally different, e.g. a passive scan on
channel 4 for a different SSID). Fix this inconsistency by always
firing off a scan when associating without a bssid.

libertas: handle mesh networks in lbs_iface_active()

2011-08-24T18:41:42+00:00

There was an extra semicolon so the if condition wasn't used.  We
checked "priv->dev" twice instead of "priv->mesh_dev".

libertas: disable functionality when interface is down

2011-08-09T19:52:02+00:00

Modify the driver so that it does not function when the interface is
down, in preparation for runtime power management.

No commands can be run while the interface is down, so the ndo_dev_stop
routine now directly does all necessary work (including asking the device
to disconnect from the network and disabling multicast functionality)
directly.

power_save and power_restore hooks are added meaning that card drivers
can take steps to turn the device off when the interface is down.

The MAC address can now only be changed when all interfaces are down;
the new address will be programmed when an interface gets brought up.
This matches mac80211 behaviour.

Also, some small cleanups/simplifications were made in the surrounding
device handling logic.

libertas: link mesh device to wiphy

2011-08-08T18:26:31+00:00

The mesh device is now exposed as an interface of the wiphy.
This exposes the mesh device to the cfg80211 interface, allowing
mesh channel selection to be reimplemented, and available to
NetworkManager as it was before.

Some header tweaking was needed in order to implement lbs_mesh_activated().

libertas: only enable mesh when interface is active

2011-07-20T19:04:41+00:00

Previously, the mesh was running whenever the appropriate hardware
and firmware was present.

Now we only run the mesh when the interface is running.

Also simplifies interface management a little.

libertas: use kernel-doc notation, fix comment style

2011-04-28T18:53:18+00:00

Convert all libertas/ files to use kernel-doc notation instead
of whatever it was (doxygen?).

Add or fix function parameters in several places.

Use expected style for multi-line comments in lots of places.

Remove erroneous /** in multiple places.
