mac80211: allow drivers to provide most station statistics

2015-01-08T14:28:06+00:00

In many cases, drivers can filter things like beacons that will
skew statistics reported by mac80211. To get correct statistics
in these cases, call drivers to obtain statistics and let them
override all values, filling values from mac80211 if the driver
didn't provide them. Not all of them make sense for the driver
to fill, so some are still always done by mac80211.

Note that this doesn't currently allow a driver to say "I know
this value is wrong, don't report it at all", or to sum it up
with a mac80211 value (as could be useful for "dropped misc"),
that can be added if it turns out to be needed.

This also gets rid of the get_rssi() method as is can now be
implemented using sta_statistics().

cfg80211: clean up beacon loss CQM event

2014-11-26T19:56:42+00:00

Having it as a sub-event for RSSI thresholds is very ugly,
but luckily no userspace actually uses the events yet.

Move the event to its own function call internally and to
its own event attribute in nl80211.

mac80211: notify drivers on sta rate table changes

2014-11-19T18:15:50+00:00

This allows drivers with a firmware or chip-based rate lookup table to
use the most recent default rate selection without having to get it from
per-packet data or explicit ieee80211_get_tx_rate calls

mac80211: allow drivers to support NL80211_SCAN_FLAG_RANDOM_ADDR

2014-11-19T17:46:09+00:00

Allow drivers to support NL80211_SCAN_FLAG_RANDOM_ADDR with software
based scanning and generate a random MAC address for them for every
scan request with the flag.

mac80211: add TDLS channel-switch Rx flow

2014-11-19T17:45:26+00:00

When receiving a TDLS channel switch request or response, parse the frame
and call a new tdls_recv_channel_switch op in the low level driver with
the parsed data.

mac80211: introduce TDLS channel switch ops

2014-11-19T17:45:21+00:00

Implement the cfg80211 TDLS channel switch ops and introduce new mac80211
ones for low-level drivers.
Verify low-level driver support for the new ops when using the relevant
wiphy feature bit. Also verify the peer supports channel switching before
passing the command down.

Add a new STA flag to track the off-channel state with the TDLS peer and
make sure to cancel the channel-switch if the peer STA is unexpectedly
removed.

mac80211: add device_timestamp to the drv_pre_channel_switch trace

2014-11-10T09:18:04+00:00

The device_timestamp value was left out of the event trace for
drv_pre_channel_switch by mistake.  Add it.

mac80211: replace restart_complete() with reconfig_complete()

2014-11-04T12:49:00+00:00

Drivers might want to know also when mac80211 has
completed reconfiguring after resume (e.g. in order
to know when frames can be passed to mac80211).

Rename restart_complete() to a more-generic reconfig_complete(),
and add a new enum to indicate the reconfiguration type.

Update the current users with the new prototype.

mac80211: add support for driver tx power reporting

2014-11-04T09:15:09+00:00

The configured tx power is often limited by hardware capabilities,
channel settings, antenna configuration, etc.

mac80211: allow channel switch with multiple channel contexts

2014-10-09T09:30:09+00:00

Channel switch with multiple channel contexts should now work fine.
Remove check that disallows switches when multiple contexts are in
use.
