Add kerneldoc for vendor request functions in rt2x00usb. Add asynchroneous vendor request function in rt2x00usb. With the availability of the asynchroneuous vendor request we can now enable LED class support for rt2500usb and rt73usb. Since LED handling is not important, it doesn't really matter if a register call fails (This solution is better then no LED class support at all). Signed-off-by:

Make use of the led triggers provided by mac80211 to control the led status. This can be enabled through a per-driver configuration option which will automatically enable the generic handler in rt2x00lib. This has been enabled for rt2500usb and rt73usb for the moment since the led class will call set_brightness in irq context which will not work correctly with the usb drivers who need to sleep.

rt2500usb initialized the SIFS and EIFS without using the values coming from rt2x000lib. After this is fixed HWMODE_{A,B,G} is now unused and can be removed in favour of the ieee80211_band enumeration which could still be usefull later. Signed-off-by: -

Recent changes to the rate structure registration broke rt2x00, the hw_value was reduced from 32bits to 16bits while rt2x00 used the full 32bits. However the way rt2x00 used the value was inflexible and needed to be changed anyway. This patch creates a array containing information for each rate, the hw_value passed to mac80211 is the index value for that array including a field to indicate if short preamble should be enabled.

This patch finishes the port and enables debug as an build option. This was tested on: Atheros AR5213A chip found (MAC: 0x59, PHY: 0x43) RF5112A multiband radio found (0x36) Note: For 2 GHz band on the above card I noticed we get negative channel numbers. Will look into this unless someone beats me to it. Example out put when loading using: sudo modprobe ath5k debug=0x00000400 Band 2 GHz: channels 26, rates 12 channels: 1 2412 00c0 0000 2 2417 00c0 0000 3 2422 00c0 0000 4 2427 00c0 0000 5 2432 00c0 0000 6 2437 00c0 0000 7 2442 00c0 0000 8 2447 00c0 0000 9 2452 00c0 0000 10 2457 00c0 0000 11 2462 00c0 0000 12 2467 00c0 0000 13 2472 00c0 0000 14 2484 00c0 0000 -498 2512 00c0 0000 -494 2532 00c0 0000 -490 2552 00c0 0000 -486 2572 00c0 0000 -482 2592 00c0 0000 -478 2612 00c0 0000 -474 2632 00c0 0000 -470 2652 00c0 0000 -466 2672 00c0 0000 -462 2692 00c0 0000 -458 2712 00c0 0000 -454 2732 00c0 0000 Band 5 GHz: channels 194, rates 8 channels: 27 5135 0140 0000 28 5140 0140 0000 [... etc ] 219 6095 0140 0000 220 6100 0140 0000 rates: 60 000b 0000 0000 90 000f 0000 0000 120 000a 0000 0000 180 000e 0000 0000 240 0009 0000 0000 360 000d 0000 0000 480 0008 0000 0000 540 000c 0000 0000 Changes to base.c, base.h Changes-licensed-under: 3-Clause-BSD Changes to debug.c, debug.h Changes-licensed-under: GPL Signed-off-by: -

Apologoes, this is a re-post of patch-04, forgot to git-add our Kconfig... New series (only 2 patches needed fixing, which I am reposting) can be found here: http://kernel.org/pub/linux/kernel/people/mcgrof/patches/ath5k/2008-02-04.v2/ Use our own Kconfig file, we'll be expanding this shortly.

Luis R. Rodriguez authored
Cleanup after API changes patch (checkpatch.pl stuff) and on ath5k_hw_channel() make use of the existing ath5k_channel_ok() instead of re-implementing the checks again. This was necessary to make the code cleaner and fit the 80-chars wide limit so sending it within the same patch. Finally make a note that we *may* eventually move cap_range stuff to struct wiphy (band frequency range capabilities). This information can later be exported to userspace, for example, and giving it access to mac80211 and drivers in general can come in handy.

When the driver registers a IEEE80211_BAND_2GHZ band, it can either be 802.11b or 802.11g. But when 802.11b rates are registered "want" will be 3 (since 4 rates are being registered, and each of those 4 rates will decrease "want"). Since this is a correct situation, there is no need to trigger a WARN_ON() for this. Signed-off-by:

Merge rate_control_pid_shift_adjust() to rate_control_pid_adjust_rate() in order to make the learning algorithm aware of constraints on rates. Also add some comments and rename variables. This fixes a bug which prevented 802.11b/g non-AP STAs from working with 802.11b only AP STAs. Signed-off-by:

This patch removes the 802.1X port acess control enable flag since it is not required. Instead, set the authorized flag for each station that we normally communicate with (WDS peers, IBSS peers and APs we're associated to) and require hostapd to set the authorized flag for all stations when port control is not enabled. Also, since I was working in that area, this documents station flags and removes the unused "permanent" one. Signed-off-by:

When checking for the next band to advance to, there was an off-by-one error that could lead to an access to an invalid array index. Additionally, the later check for scan_band >= IEEE80211_NUM_BANDS is not required since that will never be true. This also improves the comments related to that code. Signed-off-by:

Johannes Berg authored
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:

As Johannes Berg indicated the BEACON and AFTER_BEACON queue indeces in mac80211 should be removed because they are too hardware specific. This patch adds the queue index defines into rt2x00queue.h and removes the dependency of the defines inside mac80211.h. Also move rt2x00pci_beacon_update() into rt2400pci and rt2500pci individually since it is no longer a generic function since rt61 and rt2800 no longer use that. Signed-off-by:

Rework the interface handling. Delete the interface structure and replace it with a per-interface structure. This changes the way rt2x00 handles the active interface drastically. Copy ieee80211_bss_conf to the this rt2x00_intf structure during the bss_info_changed() callback function. This will allow us to reference it later, and removes the requirement for the device flag SHORT_PREAMBLE flag which is interface specific. Drivers receive the option to give the maximum number of virtual interfaces the device can handle. Virtual interface support: rt2400pci: 1 sta or 1 ap, * monitor interfaces rt2500pci: 1 sta or 1 ap, * monitor interfaces rt2500usb: 1 sta or 1 ap, * monitor interfaces rt61pci: 1 sta or 4 ap, * monitor interfaces rt73usb: 1 sta or 4 ap, * monitor interfaces At the moment none of the drivers support AP and STA interfaces simultaneously, this is a hardware limitation so future support will be very unlikely. Each interface structure receives its dedicated beacon entry, with this we can easily work with beaconing while multiple master mode interfaces are currently active. The configuration handlers for the MAC, BSSID and type are often called together since they all belong to the interface configuration. Merge the 3 configuration calls and cleanup the API between rt2x00lib and the drivers. While we are cleaning up the interface configuration anyway, we might as well clean up the configuration handler as well. Signed-off-by:

The driver should select what CRC algorithm is required when performing a checksum on the firmware. rt61pci & rt73usb require crc-itu-t rt2800pci & rt2800usb require crc-ccitt Legacy 2800pci/usb driver uses crc-itu-t + bit order reversion, but that is just inefficient especially since the end result is the same as a different algorithm which is also available as library. ;) Signed-off-by:

This will enable the creation of master mode and adhoc interfaces again. This does not mean the issues surrounding beaconing have been resolved, but this will make testing easier and perhaps we can discover which cards are actually working and which ones not. Signed-off-by:

This introduces a big queue handling overhaul, this also renames "ring" to "queues". Move queue handling into rt2x00queue.c and the matching header, use Kerneldoc to improve rt2x00 library documentation. Access to the queues is now protected under a spinlock, this to prevent race conditions which could corrupt the indexing system of the queue. Each queue entry allocates x bytes for driver/device specific data, this cleans up the queue structure significantly and improves code readability. rt2500usb no longer needs 2 entries in the beacon queue to correctly send out the guardian byte. This is now handled in the entry specific structure. rt61 and rt73 now use the correct descriptor size for beacon frames, since this data is written into the registers not the entire TXD descriptor was used but instead of a subset of it named TXINFO. Finally this also fixes numerous other bugs related to incorrect beacon handling or beacon related code. Signed-off-by:
