* b43/b43legacy: fix radio LED initializationLarry Finger2009-07-071-0/+1
| | | | | | | | | | | | | | Fix condition in which radio LED did not initialize correctly, and remove 4 compilation warnings. After the recent changes in rfkill, the radio LED used by b43/b43legacy did not always initialize correctly. Both b43 and b43legacy used the deprecated variable radio_enabled in struct ieee80211_conf. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: John W.

* cfg80211 API for channels/bitrates, mac80211 and driver conversionJohannes Berg2008-02-291-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* b43legacy: Add driver load messagesStefano Brivio2008-02-151-0/+4
| | | | | | | | | | | | | | | | | | This adds printk messages with basic information about the driver being loaded. This information includes a summary of the compiled-in features, which simplifies bug-reporting and debugging a lot. Also a firmware ID is printed. This is a unique identifier blob for a specific version of the firmware. This ID is attached to a specific version of the firmware blob in b43-fwcutter (see fwcutter git). This helps users to select the right firmware for their device. This also makes it possible to use automated scripts to fetch and extract the right firmware for the driver. (The script will grep the .ko for the "Firmware-ID: xxx" string.) While the driver might still support other versions of the firmware for backward compatibility, this will always print out the officially supported version, which people _should_ use.

* b43legacy: fix MAC control and microcode initStefano Brivio2008-01-311-19/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | This zeros out all microcode related memory before loading the microcode. This also fixes initialization of the MAC control register. The _only_ place where we overwrite the contents of the MAC control register is at the beginning of b43_chip_init(). All other places must do read() -> mask/set -> write() to not overwrite existing bits. This also adds a longer delay for waiting for the microcode to initialize itself. It seems that the current timeout is sufficient on all available devices, but there's no real reason why we shouldn't wait for up to one second. Slow embedded devices might exist. Better safe than sorry. While at it, fix naming of MACCTL values. This patch by Michael Buesch has been ported to b43legacy.

* mac80211: dont use interface indices in driversJohannes Berg2008-01-281-4/+1
| | | | | | | | | | | | | | | | This patch gets rid of the if_id stuff where possible in favour of a new per-virtual-interface structure "struct ieee80211_vif". This structure is located at the end of the per-interface structure and contains a variable length driver-use data area. This has two advantages: * removes the need to look up interfaces by if_id, this is better for working with network namespaces and performance * allows drivers to store and retrieve per-interface data without having to allocate own lists/hash tables Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

* [PATCH] mac80211: revamp interface and filter configurationJohannes Berg2007-10-101-13/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Drivers are currently supposed to keep track of monitor interfaces if they allow so-called "hard" monitor, and they are also supposed to keep track of multicast etc. This patch changes that, replaces the set_multicast_list() callback with a new configure_filter() callback that takes filter flags (FIF_*) instead of interface flags (IFF_*). For a driver, this means it should open the filter as much as necessary to get all frames requested by the filter flags. Accordingly, the filter flags are named "positively", e.g. FIF_ALLMULTI. Multicast filtering is a bit special in that drivers that have no multicast address filters need to allow multicast frames through when either the FIF_ALLMULTI flag is set or when the mc_count value is positive. At the same time, drivers are no longer notified about monitor interfaces at all, this means they now need to implement the start() and stop() callbacks and the new change_filter_flags() callback. Also, the start()/stop() ordering changed, start() is now called *before* any add_interface() as it really should be, and stop() after any remove_interface(). The patch also changes the behaviour of setting the bssid to multicast for scanning when IEEE80211_HW_NO_PROBE_FILTERING is set; the IEEE80211_HW_NO_PROBE_FILTERING flag is removed and the filter flag FIF_BCN_PRBRESP_PROMISC introduced. This is a lot more efficient for hardware like b43 that supports it and other hardware can still set the BSSID to all-ones.
