2008-06-30build algorithms into the mac80211 moduleAdrian Bunk1-22/+9
The old infrastructure was: - the default algorithm is built into mac80211 - other algorithms get into their own modules The implementation of this complicated scheme was horrible (just look at net/mac80211/Makefile), and anyone adding a new algorithm would most likely not get it right at his first attempt. This patch therefore builds all enabled algorithms into the mac80211 module. The user interface for the rate control algorithms changes as follows: - first the user can choose which algorithms to enable (currently only MAC80211_RC_PID is available) - if more than one algorithm is enabled (currently not possible since only one algorithm is present) the user then chooses the default one Note: - MAC80211_RC_PID is always enables for CONFIG_EMBEDDED=n Technical changes: - all selected algorithms get into the mac80211 module - net/mac80211/Makefile can now become much less complicated - support for rc80211_pid_algo.c being modular is no longer required - this includes unexporting mesh_plink_broken Signed-off-by: Adrian Bunk <bunk@kernel.org> Signed-off-by: John W.

2008-05-21mac80211: use multi-queue master netdeviceJohannes Berg1-1/+13
This patch updates mac80211 and drivers to be multi-queue aware and use that instead of the internal queue mapping. Also does a number of cleanups in various pieces of the code that fall out and reduces internal mac80211 state size. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

2008-04-27wireless: Fix compile error with wifi & ledsLuca Tettamanti1-1/+3
Fix build error caused by commit e82404ad612ebabc65d15c3d59b971cb35c3ff36 ("iwlwifi: Select LEDS_CLASS.") from David Miller: Since MAC80211_LEDS is selected by wireless drivers it must select its own dependencies otherwise a build error may occur (kbuild will select the symbol regardless of "depends" constraints).

2008-03-06mac80211: fix mesh endianness sparse warnings and unmark it as brokenLuis Carlos Cobo1-1/+1
This patch fixes all the mesh related endianness warnings reported by sparse. As they were the reason why Johannes marked mesh as BROKEN, that flag has been removed.

2008-02-01mac80211: make alignment warning optionalJohannes Berg1-0/+12
Driver authors should be aware of the alignment requirements, but not everybody cares about the warning. This patch makes it depend on a new Kconfig symbol MAC80211_DEBUG_PACKET_ALIGNMENT which can be enabled regardless of MAC80211_DEBUG and is recommended for driver authors (only). This also restricts the warning to data packets so other packets need not be realigned to not trigger the warning. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-01-28mac80211: better rate control algorithm selectionJohannes Berg1-19/+18
This patch changes mac80211's Kconfig/Makefile to: * select between the PID and the SIMPLE rate control algorithm as default * always allow tri-state for the rate control algorithms, building those that are selected 'y' into the mac80211 module (if that is a module, otherwise all into the kernel) * force the default rate control algorithm to be built into mac80211 It also makes both rate control algorithms proper modules again with MODULE_LICENSE etc. Only if EMBEDDED is the user allowed to select "NONE" as default which will cause no algorithm to be selected, this will work only when the driver brings one itself (e.g. iwlwifi drivers).

2008-01-28mac80211: make PID rate control algorithm the defaultStefano Brivio1-13/+59
This makes the new PID TX rate control algorithm the default instead of the rc80211_simple rate control algorithm. The simple algorithm was flawed in several ways: it wasn't responsive at all and didn't age the information it was relying on properly. The PID algorithm allows us to tune characteristics such as responsiveness by adjusting parameters and was found to generally behave better. The default algorithm can be overridden to select simple instead. Which ever algorithm is the default is included as part of the mac80211 module automatically. The other algorithm (simple vs. pid) can be selected for inclusion as well. If EMBEDDED is selected then the choice is available to have no default specified and neither algorithm included in mac80211. The default algorithm can be set through a modparam. While at it, mark rc80211-simple as deprecated, and schedule it for removal. Signed-off-by: Stefano Brivio <stefano.brivio@polimi.it> Signed-off-by: John W.

2007-11-10mac80211: fix MAC80211_RCSIMPLE KconfigJohannes Berg1-2/+2

2007-11-10mac80211: make simple rate control algorithm built-inJohannes Berg1-0/+12
Too frequently people do not have module autoloading enabled or fail to install the rate control module correctly, hence their hardware probing fails due to no rate control algorithm being available. This makes the 'simple' algorithm built into the mac80211 module unless EMBEDDED is enabled in which case it can be disabled (eg. if the wanted driver requires another rate control algorithm.)
