mac80211: fix debugfs netdev rename

2008-10-15T00:48:00+00:00

If, for some reason, a netdev has no debugfs dir, we shouldn't
try to rename that dir.

mac80211: remove beacon counters

2008-09-15T20:48:26+00:00

The beacon counters mac80211 keeps are only used for debugfs,
unfortunately, they are incorrect for many hardware designs,
namely any design that has a beacon template. Hence, remove the
counters so we don't create the impression they are usable.

This also allows removing the beacon MESH #ifdef again.

mac80211: use nl80211 interface types

2008-09-15T20:48:23+00:00

There's really no reason for mac80211 to be using its
own interface type defines. Use the nl80211 types and
simplify the configuration code a bit: there's no need
to translate them any more now.

mac80211: split off mesh handling entirely

2008-09-15T20:48:20+00:00

This patch splits off mesh handling from the STA/IBSS.
Unfortunately it increases mesh code size a bit, but I
think it makes things clearer. The patch also reduces
per-interface run-time memory usage.

Also clean up a few places where ifdef is not required.

mac80211: Fix debugfs file add/del for netdev

2008-08-27T00:06:33+00:00

Previous version was using incorrect union structures for non-AP
interfaces when adding and removing max_ratectrl_rateidx and
force_unicast_rateidx entries. Depending on the vif type, this ended
up in corrupting debugfs entries since the dentries inside different
union structures ended up going being on top of eachother.. As the
end result, debugfs files were being left behind with references to
freed data (instant kernel oops on access) and directories were not
removed properly when unloading mac80211 drivers. This patch fixes
those issues by using only a single union structure based on the vif
type.

mac80211: revamp virtual interface handling

2008-07-14T18:30:07+00:00

This patch revamps the virtual interface handling and makes the
code much easier to follow. Fewer functions, better names, less
spaghetti code.

mac80211: make master netdev handling sane

2008-07-14T18:30:06+00:00

Currently, almost every interface type has a 'bss' pointer
pointing to BSS information. This BSS information, however,
is for a _local_ BSS, not for the BSS we joined, so having
it on a STA mode interface makes little sense, but now they
have it pointing to the master device, which is an AP mode
virtual interface. However, except for some bitrate control
data, this pointer is only used in AP/VLAN modes (for power
saving stations.)

Overall, it is not necessary to even have the master netdev
be a valid virtual interface, and it doesn't have to be on
the list of interfaces either.

This patch changes the master netdev to be special, it now
 - no longer is on the list of virtual interfaces, which
   lets me remove a lot of tests for that
 - no longer has sub_if_data attached, since that isn't used

Additionally, this patch changes some vlan/ap mode handling
that is related to these 'bss' pointers described above (but
in the VLAN case they actually make sense because there they
point to the AP they belong to); it also adds some debugging
code to IEEE80211_DEV_TO_SUB_IF to validate it is not called
on the master netdev any more.

mac80211: remove channel use statistics

2008-05-22T01:48:17+00:00

The useless channel use statistics are quite a lot of code, currently
use integer divisions in the packet fast path, are rather inaccurate
since they do not account for retries and finally nobody even cares.
Hence, remove them completely.

mac80211: a few code cleanups

2008-05-07T19:02:11+00:00

This has some code cleanups (some inspired by checkpatch), I got
bored at probably a third of the output though so if somebody
else wants to...

mac80211: rename files

2008-04-08T20:44:45+00:00

This patch renames all mac80211 files (except ieee80211_i.h) to get rid
of the useless ieee80211_ prefix.
