{mac|nl}80211: Add station connected time

2011-04-12T20:58:47+00:00

Add station connected time in debugfs. This will be helpful to get a
measure of stability of the connection and for debugging stress issues

mac80211: Add timeout to BA session start API

2010-12-15T22:03:59+00:00

Allow drivers or rate control algorithms to specify BlockAck session
timeout when initiating an ADDBA transaction. This is useful in cases
where maintaining persistent BA sessions does not incur any overhead.

The current timeout value of 5000 TUs is retained for all non ath9k/ath9k_htc
drivers.

mac80211: fix RX aggregation locking

2010-11-29T20:30:30+00:00

The RX aggregation locking documentation was
wrong, which led Christian to also code the
timer timeout handling for it somewhat wrongly.

Fix the documentation, the two places that
need to hold the reorder lock across accesses
to the structure, and the debugfs code that
should just use RCU.

Also, remove acquiring the sta->lock across
reorder timeouts since it isn't necessary, and
change a few places to GFP_KERNEL because the
code path here doesn't need atomic allocations
as I noticed when reviewing all this.

mac80211: refactor debugfs function generation code

2010-11-15T18:24:48+00:00

refactor mac80211 debugfs code by using a format© function, instead of
duplicating the code for each generated function.

this change reduces about 600B from mac80211.ko

mac80211: avoid transmitting delBA to old AP

2010-10-06T20:30:40+00:00

When roaming while we have active BA session,
we can end up transmitting delBA frames to
the old AP while we're already on the new AP's
channel, which can cause warnings.

Simply avoid sending those frames, but still
tear down the internal session state, since
they are not really necessary anyway as we
will implicitly disassociate when sending the
association to the new AP.

net/wireless: use generic_file_llseek in debugfs

2010-09-16T08:33:08+00:00

The default llseek operation is changing from
default_llseek to no_llseek, so all code relying on
the current behaviour needs to make that explicit.

The wireless driver infrastructure and some of the drivers
make use of generated debugfs files, so they cannot
be converted by our script that automatically determines
the right operation.

All these files use debugfs and they typically rely
on simple_read_from_buffer, so the best llseek operation
here is generic_file_llseek.

mac80211: make TX aggregation start/stop request async

2010-06-14T19:39:27+00:00

When the driver or rate control requests starting
or stopping an aggregation session, that currently
causes a direct callback into the driver, which
could potentially cause locking problems. Also,
the functions need to be callable from contexts
that cannot sleep, and thus will interfere with
making the ampdu_action callback sleeping.

To address these issues, add a new work item for
each station that will process any start or stop
requests out of line.
