mac80211: add time synchronisation with BSS for assoc

2012-07-12T10:10:46+00:00

Some drivers (iwlegacy, iwlwifi and rt2x00) today use the
bss_conf.last_tsf value. By itself though that value is
completely worthless since it may be ancient. What really
is needed is synchronisation between some device time and
the TSF.

To clarify this, rename bss_conf.last_tsf to sync_tsf and
add sync_device_ts which is obtained from rx_status which
gets a new field device_timestamp for this purpose. This
is intentionally not using the mactime field since that
is used for other things and in IBSS is expected to sync
with the IBSS's TSF which isn't necessarily true for the
device timestamp.

Also, since we have the information and it's useful even
before the connection has been established, give all the
timing details to the driver before authenticating.

mac80211: optimize ieee80211_rx_status struct layout

2012-07-12T10:10:45+00:00

We waste a lot of space in this struct because it uses
int values where smaller ones would be sufficient. The
upcoming A-MPDU information needs some space, optimize
the struct now.

mac80211: remove ieee80211_key_removed

2012-07-09T12:49:15+00:00

This API call was intended to be used by drivers
if they want to optimize key handling by removing
one key when another is added. Remove it since no
driver is using it. If needed, it can always be
added back.

mac80211: add TX prepare API

2012-07-03T11:50:34+00:00

Some drivers require setup before being able to send
management frames in managed mode, in particular in
multi-channel cases.

Introduce API to allow the drivers to do such setup
while being able to sleep waiting for the setup to
finish in the device. This isn't possible inside the
TX call since that can't sleep.

A future patch may also restructure the TX retry to
wait for the driver to report the frame status, as
suggested by Arik in
http://mid.gmane.org/CA+XVXffKSEL6ZQPQ98x-zO-NL2=TNF1uN==mprRyUmAaRn254g@mail.gmail.com

mac80211: reduce IEEE80211_TX_MAX_RATES

2012-07-03T11:48:37+00:00

IEEE80211_TX_MAX_RATES can be reduced from 5 to 4 as there
is no current hardware supporting a rate chain with 5 multi
rate stages (mrr), so 4 mrr stages are sufficient.

The memory that is freed within the ieee80211_tx_info struct
will be used in the upcoming Transmission Power Control (TPC)
implementation.

mac80211: remove tx_frags driver callback

2012-07-02T13:40:18+00:00

The implementation of tx_frags is buggy due to
not handling queue stop, and there's no driver
implementing it so remove it.

mac80211: don't expose ieee80211_add_srates_ie()

2012-06-28T08:35:50+00:00

This and ieee80211_add_ext_srates_ie() aren't
exported, so can't be used by drivers anyway,
but there's also no reason that they should be
so make them private to mac80211 and use sdata
instead of vif arguments.

mac80211: clean up debugging

2012-06-24T09:32:29+00:00

There are a few things that make the logging and
debugging in mac80211 less useful than it should
be right now:
 * a lot of messages should be pr_info, not pr_debug
 * wholesale use of pr_debug makes it require *both*
   Kconfig and dynamic configuration
 * there are still a lot of ifdefs
 * the style is very inconsistent, sometimes the
   sdata->name is printed in front

Clean up everything, introducing new macros and
separating out the station MLME debugging into
a new Kconfig symbol.
