2008-11-10b43/legacy: remove SSID codeJohannes Berg
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 <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-10-31mac80211/drivers: rewrite the rate control APIJohannes Berg
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 Berg
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.

2008-09-05cfg80211: keep track of supported interface modesLuis R. Rodriguez
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 Berg
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 Berg
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.

2008-07-14mac80211: revamp beacon configurationJohannes Berg
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.

This is a rewrite of the DMA API for SSB devices. This is needed, because the old (non-existing) "API" made too many bad assumptions on the API of the host-bus (PCI).

2008-05-14mac80211: use hardware flags for signal/noise unitsBruno Randolf
trying to clean up the signal/noise code. the previous code in mac80211 had confusing names for the related variables, did not have much definition of what units of signal and noise were provided and used implicit mechanisms from the wireless extensions. this patch introduces hardware capability flags to let the hardware specify clearly if it can provide signal and noise level values and which units it can provide. this also anticipates possible new units like RCPI in the future. for signal: IEEE80211_HW_SIGNAL_UNSPEC - unspecified, unknown, hw specific IEEE80211_HW_SIGNAL_DB - dB difference to unspecified reference point IEEE80211_HW_SIGNAL_DBM - dBm, difference to 1mW for noise we currently only have dBm: IEEE80211_HW_NOISE_DBM - dBm, difference to 1mW if IEEE80211_HW_SIGNAL_UNSPEC or IEEE80211_HW_SIGNAL_DB is used the driver has to provide the maximum value (max_signal) it reports in order for applications to make sense of the signal values. i tried my best to find out for each driver what it can provide and update it but i'm not sure (?) for some of them and used the more conservative guess in doubt. this can be fixed easily after this patch has been merged by changing the hardware flags of the driver.

This is in particular true for rt2x00 who needs to know the key algorithm and whether it is a shared or pairwise key. By passing the ieee80211_key_conf pointer it assures us that drivers can make full use of all information that it should know about a particular key. Additionally this patch updates all drivers to grab the hw_key_idx from the ieee80211_key_conf structure. v2: Removed bogus u16 cast v3: Add warning about ieee80211_tx_control pointers v4: Update warning about ieee80211_tx_control pointers Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Acked-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.
