* zd1211rw: Fix FSF address in file headersJeff Kirsher2013-12-111-2/+1
| | | | | | | | | | | | | Several files refer to an old address for the Free Software Foundation in the file header comment. Resolve by replacing the address with the URL <http://www.gnu.org/licenses/> so that we do not have to keep updating the header comments anytime the address changes.

* wireless: Remove casts to same typeJoe Perches2012-06-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adding casts of objects to the same type is unnecessary and confusing for a human reader. For example, this cast: int y; int *p = (int *)&y; I used the coccinelle script below to find and remove these unnecessary casts. I manually removed the conversions this script produces of casts with __force, __iomem and __user. @@ type T; T *p; @@ - (T *)p + p Neatened the mwifiex_deauthenticate_infra function which was doing odd things with array pointers and not using is_zero_ether_addr.

* zd1211rw: Fix TX status reporting in order to have proper rate controlBenoit PAPILLAULT2009-10-271-1/+17
| | | | | | | | | | | | | | | | First, we reduce the number of hardware retries to 0 (ie 2 real retries for each rate). Next, when we report the retries to mac80211, we always report a retry count of 1 (it seems to be 2 in fact, but using 2 seems to lead to wrong performance for some reason). We use a state machine to determine the real fate of a packet based on the 802.11 ACK and what the Zydas hardware is saying when a real retry occurs. The real retry rates are encoded in a static array. It has been tested with both zd1211 and zd1211b hardware. Of course, since the Zydas hardware is not reporting retries accurately, we are just doing our best in order to get the best performance (ie higher throughput).

Previously missing beaconing support has been added. This might also help implement a currently missing ah-hoc mode. Support for interrupts from the device have been added, but we are not handling most of them. Mesh interfaces are considered associated as long as the interface is up.

* [PATCH] zd1211rw: monitor all packetsUlrich Kunitz2007-10-101-5/+0
| | | | | | | | | | | | | | | | | | | | | | | While in monitor mode the zd1211rw received only a limited set of packets. This patch forwards now all packets the device receives. Notify that while monitoring no FCS checks are done; so strange packets might appear in the network sniffer of your choice. ATTENTION: Support for multiple interfaces on a single ZD1211 device is currently broken. So this code works only on the first interface. Here is an example to put the device in monitor mode. iwconfig wlan0 mode monitor ifconfig wlan0 up iwconfig wlan0 channel 10 [dsd@gentoo.org: backport to mainline] Signed-off-by: Ulrich Kunitz <kune@deine-taler.de> Signed-off-by: Daniel Drake <dsd@gentoo.org> Signed-off-by: John W.

* [PATCH] zd1211rw: Defer firmware load until first ifupDaniel Drake2007-07-101-5/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | While playing with the firmware a while back, I discovered a way to access the device's entire address space before the firmware has been loaded. Previously we were loading the firmware early on (during probe) so that we could read the MAC address from the EEPROM and register a netdevice. Now that we can read the EEPROM without having firmware, we can defer firmware loading until later while still reading the MAC address early on. This has the advantage that zd1211rw can now be built into the kernel -- previously if this was the case, zd1211rw would be loaded before the filesystem is available and firmware loading would fail. Firmware load and other device initialization operations now happen the first time the interface is brought up. Some architectural changes were needed: handling of the is_zd1211b flag was moved into the zd_usb structure, MAC address handling was obviously changed, and a preinit_hw stage was added (the order is now: init, preinit_hw, init_hw).

* [PATCH] zd1211rw: Add UW2453 RF supportDaniel Drake2007-07-081-0/+3
| | | | | | | | | | | | | | | | | | | This patch adds support for another radio appearing in new devices: the Ubec UW2453. It's more complicated than the other RF's we support, but Ubec publish full tech specs so we're able to understand the vendor code relatively well. Now that we support UW2453, we also support Atheros' new USB chip: the AR5007UG. From the little info we have, this appears to be just a rebranded ZD1211B. This RF code doesn't work very well -- lots more TX/RX errors than the other RFs. However, the vendor driver doesn't do any better, so this is all we can do for now.

| | | | | | | | | | | | This change allows RF drivers to provide their own 6M band edge patching implementation, while providing a generic implementation shared by most currently supported RF's.

| | | | | | | | | | | | | | | Due to conflicting/confusing defines in the vendor driver, we were reading E2P_PHY_REG from the wrong location. CR157 patching was slightly incorrect in that the vendor driver only patches in an 8-bit value, whereas we were patching 24 bits. Additionally, CR157 patching was happening on both zd1211 and zd1211b, but this should only happen on zd1211.

* [PATCH] zd1211rw: Remove addressing abstractionDaniel Drake2007-02-051-40/+49
| | | | | | | | | | | | | | | | | | | | | | | | Instead of passing our own custom 32-bit addresses around and translating them, this patch makes all our register address constants absolute and removes the translation. There are two ugly parts: - fw_reg_addr() is needed to compute addresses of firmware registers, as this is dynamic based upon firmware - inc_addr() needs a small hack to handle byte vs word addressing However, both of those are only small, and we don't use fw_regs a whole lot anyway. The bonuses here include simplicity and improved driver readability. Also, the fact that registers are now referenced by 16-bit absolute addresses (as opposed to 32-bit pseudo addresses) means that over 2kb compiled code size has been shaved off.

* [PATCH] zd1211rw: Consistency for address space constantsDaniel Drake2007-02-051-53/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | The zd1211rw address space has confused me once too many times. This patch introduces the following naming notation: Memory space is split into segments (cr, fw, eeprom) and segments may contain components (e.g. boot code inside eeprom). These names are arbitrary and only for the description below: x_START: Absolute address of segment start (previously these were named such as CR_BASE_OFFSET, but they weren't really offsets unless you were considering them as an offset to 0) x_LEN: Segment length x_y_LEN: Length of component y of segment x x_y_OFFSET: Relative address of component y into segment x. The absolute address for this component is (x_START + x_y_OFFSET) I also renamed EEPROM registers to EEPROM data. These 'registers' can't be written to using standard I/O and really represent predefined data from the vendor. Signed-off-by: Daniel Drake <dsd@gentoo.org> Signed-off-by: John W.

* [PATCH] ZyDAS ZD1211 USB-WLAN driverDaniel Drake2006-07-051-0/+825
There are 60+ USB wifi adapters available on the market based on the ZyDAS ZD1211 chip. Unlike the predecessor (ZD1201), ZD1211 does not have a hardware MAC, so most data operations are coordinated by the device driver. The ZD1211 chip sits alongside an RF transceiver which is also controlled by the driver. Our driver currently supports 2 RF types, we know of one other available in a few marketed products which we will be supporting soon. Our driver also supports the newer revision of ZD1211, called ZD1211B. The initialization and RF operations are slightly different for the new revision, but the main difference is 802.11e support. Our driver does not support the QoS features yet, but we think we know how to use them. This driver is based on ZyDAS's own GPL driver available from www.zydas.com.tw. ZyDAS engineers have been responsive and supportive of our efforts, so thumbs up to them. Additionally, the firmware is redistributable and they have provided device specs. This driver has been written primarily by Ulrich Kunitz and myself. Graham Gower, Greg KH, Remco and Bryan Rittmeyer have also contributed. The developers of ieee80211 and softmac have made our lives so much easier- thanks! We maintain a small info-page: http://zd1211.ath.cx/wiki/DriverRewrite If there is enough time for review, we would like to aim for inclusion in 2.6.18. The driver works nicely as a STA, and can connect to both open and encrypted networks (we are using software-based encryption for now). We will work towards supporting more advanced features in the future (ad-hoc, master mode, 802.11a, ...). Signed-off-by: Daniel Drake <dsd@gentoo.org> Signed-off-by: John W.
