2009-05-20b43legacy: Remove unnecessary MMIO in interrupt hotpathStefano Brivio3-59/+25
This removes unnecessary MMIO accesses in the interrupt hotpath. The patch by Michael Buesch for b43 has been ported to b43legacy. Signed-off-by: Stefano Brivio <[email protected]> Tested-by: Larry Finger <[email protected]> Signed-off-by: John W. Linville <[email protected]>
2009-05-06mac80211: unify config_interface and bss_info_changedJohannes Berg1-39/+24
The config_interface method is a little strange, it contains the BSSID and beacon updates, while bss_info_changed contains most other BSS information for each interface. This patch removes config_interface and rolls all the information it previously passed to drivers into bss_info_changed. Signed-off-by: Johannes Berg <[email protected]> Signed-off-by: John W. Linville <[email protected]>
2009-05-06mac80211: clean up beacon interval settingsJohannes Berg1-5/+5
We currently have two beacon interval configuration knobs: hw.conf.beacon_int and vif.bss_info.beacon_int. This is rather confusing, even though the former is used when we beacon ourselves and the latter when we are associated to an AP. This just deprecates the hw.conf.beacon_int setting in favour of always using vif.bss_info.beacon_int. Since it touches all the beaconing IBSS code anyway, we can also add support for the cfg80211 IBSS beacon interval configuration easily. NOTE: The hw.conf.beacon_int setting is retained for now due to drivers still using it -- I couldn't untangle all drivers, some are updated in this patch.

2009-04-22b43legacy: Clean up beacon IRQLarry Finger4-51/+121
This patch ports commit c97a4ccc1fad35d3 "b43: Fix beacon BH update" to b43legacy. It fixes beacon updating in the bottomhalf. In case the device is busy, we will defer to later in the IRQ handler.

This patch ports the beaconing fixes from commit a82d992261f "b43: Beaconing fixes" to b43legacy. Basically it prevents the card from triggering the beacon IRQ over and over again.

Auto-depend on HW_RANDOM, rather than "select"ing it. This way the user has the choice to enable or disable HWRNG support. Signed-off-by: Larry Finger <[email protected]> Signed-off-by: John W. Linville <[email protected]>
2009-04-22rfkill: remove user_claim stuffJohannes Berg1-1/+0
Almost all drivers do not support user_claim, so remove it completely and always report -EOPNOTSUPP to userspace. Since userspace cannot really drive rfkill _anyway_ (due to the odd restrictions imposed by the documentation) having this code is just pointless.

2009-02-09b43legacy: fix led namingDanny Kukawka1-4/+4
Fixed led device naming for the b43legacy driver. Due to the documentation of the led subsystem/class the naming should be "devicename:colour:function" while not applying sections should be left blank. This should lead to e.g. "b43legacy-%s::rx" instead of "b43legacy-%s:rx". Signed-off-by: Danny Kukawka <[email protected]> Acked-by: Larry Finger <[email protected]> Signed-off-by: John W.

2009-01-29wireless: restrict to 32 legacy ratesJohannes Berg1-1/+1
Since the standards only define 12 legacy rates, 32 is certainly a sane upper limit and we don't need to use u64 everywhere. Add sanity checking that no more than 32 rates are registered and change the variables to u32 throughout. Signed-off-by: Johannes Berg <[email protected]> Signed-off-by: John W.

2008-11-10b43/legacy: remove SSID codeJohannes Berg1-24/+0
The SSID programmed into the device is used by the ucode only to reply to probe requests, a functionality we disable anyway because it doesn't fit with the mac80211/hostapd programming model. Therefore, it isn't useful to program the SSID into device. Signed-off-by: Johannes Berg <[email protected]> Signed-off-by: John W. Linville <[email protected]>
2008-10-31mac80211/drivers: rewrite the rate control APIJohannes Berg5-25/+82
So after the previous changes we were still unhappy with how convoluted the API is and decided to make things simpler for everybody. This completely changes the rate control API, now taking into account 802.11n with MCS rates and more control, most drivers don't support that though.

2008-10-31mac80211: introduce hw config change flagsJohannes Berg1-1/+2
This makes mac80211 notify the driver which configuration actually changed, e.g. channel etc. No driver changes, this is just plumbing, driver authors are expected to act on this if they want to. Also remove the HW CONFIG debug printk, it's incorrect, often we configure something else. Signed-off-by: Johannes Berg <[email protected]> Signed-off-by: John W. Linville <[email protected]>

2008-09-11b43legacy: Fix failure in rate-adjustment mechanismLarry Finger1-1/+1
A coding error present since b43legacy was incorporated into the kernel has prevented the driver from using the rate-setting mechanism of mac80211.

2008-09-05cfg80211: keep track of supported interface modesLuis R. Rodriguez1-0/+5
It is obviously good for userspace to know up front which interface modes a given piece of hardware might support (even if adding such an interface might fail later because of concurrency issues), so let's make cfg80211 aware of that. For good measure, disallow adding interfaces in all other modes so drivers don't forget to announce support for one mode when they add it.

2008-07-29mac80211: partially fix skb->cb useJohannes Berg1-1/+1
This patch fixes mac80211 to not use the skb->cb over the queue step from virtual interfaces to the master. The patch also, for now, disables aggregation because that would still require requeuing, will fix that in a separate patch. There are two other places (software requeue and powersaving stations) where requeue can happen, but that is not currently used by any drivers/not possible to use respectively.

2008-07-14mac80211: fix TX sequence numbersJohannes Berg1-2/+1
This patch makes mac80211 assign proper sequence numbers to QoS-data frames. It also removes the old sequence number code because we noticed that only the driver or hardware can assign sequence numbers to non-QoS-data and especially management frames in a race-free manner because beacons aren't passed through mac80211's TX path. This patch also adds temporary code to the rt2x00 drivers to not break them completely, that code will have to be reworked for proper sequence numbers on beacons. It also moves sequence number assignment down in the TX path so no sequence numbers are assigned to frames that are dropped. Signed-off-by: Johannes Berg <[email protected]> Signed-off-by: John W. Linville <[email protected]>
2008-07-14mac80211: revamp beacon configurationJohannes Berg1-28/+17
This patch changes mac80211's beacon configuration handling to never pass skbs to the driver directly but rather always require the driver to use ieee80211_beacon_get(). Additionally, it introduces "change flags" on the config_interface() call to enable drivers to figure out what is changing. Finally, it removes the beacon_update() driver callback in favour of having IBSS beacon delivered by ieee80211_beacon_get() as well.

2008-07-08b43legacy: Remove switch statement with 64-bit indexLarry Finger1-15/+51
The gcc 3.4 fork used to compile the MN10300 port emits unwanted __ucmpdi2() calls for switch statements that use a 64bit value.
