Some devices implement the entire rate control in
firmware in some way, like wl1271 or like iwlwifi
which does some things in software but not a lot.
Therefore generic software rate control is rather
useless for them and just adds avoidable overhead
to the transmit path.It's fairly simple to let drivers indicate that
they do not need rate control, but they need to
fulfil a number of conditions that we encode in
WARN_ONs.Signed-off-by: Johannes Berg

We can save a lot of code and pointers in the structs
by using debugfs_remove_recursive().First, change cfg80211 to use debugfs_remove_recursive()
so that drivers do not need to clean up any files they
added to the per-wiphy debugfs (if and only if they are
ok to be accessed until after wiphy_unregister!).Then also make mac80211 use debugfs_remove_recursive()
where necessary -- it need not remove per-wiphy files
as cfg80211 now removes those, but netdev etc. files
still need to be handled but can now be removed without
needing struct dentry pointers to all of them.Signed-off-by: Johannes Berg

I suspect that some driver bugs can cause queues to be
stopped while they shouldn't be, but it's hard to find
out whether that is the case or not without having any
visible information about the queues. This adds a file
to debugfs that allows us to see the queues' statuses.Signed-off-by: Johannes Berg

This moves the cfg80211 specific stuff to new cfg80211 debugfs
entries. Non-mac80211 will also get these entries now. There were
only 4 which we take:rts_threshold
fragmentation_threshold
short_retry_limit
long_retry_limitSigned-off-by: Luis R. Rodriguez

There's this internal wifi_wme_noack_test variable that
we use to set the QoS control if set. For one, it is
unlikely that it is set. Secondly, if set it needs to
influence the IEEE80211_TX_CTL_NO_ACK TX control flag,
and finally we should also be able to set it at all, so
make it available in debugfs.Signed-off-by: Johannes Berg

In order to later add tracing or verifications to the driver
calls mac80211 makes, this patch adds static inline wrappers
for all operations.All calls are now written as
drv_(local, ...);
instead of
local->ops->(&local->hw, ...);
Where necessary, the wrappers also do existence checking and
return default values as appropriate.Signed-off-by: Johannes Berg

Add new nl80211 attributes that can be used with NL80211_CMD_SET_WIPHY
and NL80211_CMD_GET_WIPHY to manage fragmentation/RTS threshold and
retry limits.Since these values are stored in struct wiphy, remove the local copy
from mac80211 where feasible (frag & rts threshold). The retry limits
are currently needed in struct ieee80211_conf, but these could be
eventually removed since the driver should have access to the values
in struct wiphy.Signed-off-by: Jouni Malinen

When mac80211 resumes, it currently doesn't reconfigure the interfaces
entirely and also doesn't reconfigure BSS information -- fix this.Also, to be able to test this, add a debugfs file that just calls
the suspend/resume code to see what happens when we go through that,
without needing the time-consuming suspend/resume cycle.(Original version broke the build for CONFIG_PM=n. Define alternative
functions for that situation. -- JWL)Signed-off-by: Johannes Berg

The bridge_packets configuration really should be per virtual
interface (theoretically per AP/VLAN, but this is much easier);
there currently is no way to set it yet though. Also invert
the option to "NO_BRIDGE_PACKETS" so the default is to bridge.While at it, also document the flags properly.

This
* makes the queue number passed to drivers a u16
(as it will be with skb_get_queue_mapping)
* removes the useless queue number defines
* splits hw->queues into hw->queues/ampdu_queues
* removes the debugfs files for per-queue counters
* removes some dead QoS code
* removes the beacon queue configuration for IBSS
so that the drivers now never get a queue number
bigger than (hw->queues + hw->ampdu_queues - 1)
for tx and only in the range 0..hw->queues-1 for
conf_tx.Signed-off-by: Johannes Berg

This patch renames all mac80211 files (except ieee80211_i.h) to get rid

Unfortunately, debugfs can be made to access invalid memory by
open()ing a file and then waiting until the corresponding debugfs
file has been removed (and, probably, the underlying object.)That could be exploited by any user if the user is able to open
debugfs files and can cause networking devices, STA entries or
similar to disappear which is quite easy to do.Hence, all debugfs files should be root-only.

This patch creates new cfg80211 wiphy API for channel and bitrate
registration and converts mac80211 and drivers to the new API. The
old mac80211 API is completely ripped out. All drivers (except ath5k)
are updated to the new API, in many cases I expect that optimisations
can be done.Along with the regulatory code I've also ripped out the
IEEE80211_HW_DEFAULT_REG_DOMAIN_CONFIGURED flag, I believe it to be
unnecessary if the hardware simply gives us whatever channels it wants
to support and we then enable/disable them as required, which is pretty
much required for travelling.Additionally, the patch adds proper "basic" rate handling for STA
mode interface, AP mode interface will have to have new API added
to allow userspace to set the basic rate set, currently it'll be
empty... However, the basic rate handling will need to be moved to
the BSS conf stuff.I do expect there to be bugs in this, especially wrt. transmit
power handling where I'm basically clueless about how it should work.Signed-off-by: Johannes Berg
