mac802154: basic ieee802.15.4 device structures The IEEE 802.15.4 Working Group focuses on the standardization of the bottom two layers of ISO/OSI protocol stack: Physical (PHY) and MAC. The MAC layer provides access control to a shared channel and reliable data delivery. The main functions performed by the MAC sublayer are: association and disassociation, security control, optional star network topology functions, such as beacon generation and Guaranteed Time Slots (GTSs) management, generation of ACK frames (if used), and, finally, application support for the two possible network topologies described in the standard. This is an initial commit which describes main data structures needed for ieee802.15.4 compatible devices representation in the MAC layer.

ieee802154: add header structs with endiannes and operations This patch provides a set of structures to represent 802.15.4 MAC headers, and a set of operations to push/pull/peek these structs from skbs. We cannot simply pointer-cast the skb MAC header pointer to these structs, because 802.15.4 headers are wildly variable - depending on the first three bytes, virtually all other fields of the header may be present or not, and be present with different lengths. The new header creation/parsing routines also support 802.15.4 security headers, which are currently not supported by the mac802154 implementation of the protocol.

ieee802154: rework cca setting The current cca setting handle is a driver specific call. We need to introduce some 802.15.4 specific layer and mapping 802.15.4 cca modes to driver specific ones inside the 802.15.4 driver. This patch will add such 802.15.4 layer and mapping the cca settings to driver specific ones.

mac802154: add wpan device-class support Every real 802.15.4 transceiver, which works with software MAC layer, can be classified as a wpan device in this stack. So the wpan device implementation provides missing link in datapath between the device drivers and the Linux network queue. According to the IEEE 802.15.4 standard each packet can be one of the following types: - beacon - MAC layer command - ACK - data This patch adds support for the data packet-type only, but this is enough to perform data transmission and receiving over radio.

mac802154: basic ieee802.15.4 device structures The IEEE 802.15.4 Working Group focuses on the standardization of the bottom two layers of ISO/OSI protocol stack: Physical (PHY) and MAC. The MAC layer provides access control to a shared channel and reliable data delivery. The main functions performed by the MAC sublayer are: association and disassociation, security control, optional star network topology functions, such as beacon generation and Guaranteed Time Slots (GTSs) management, generation of ACK frames (if used), and, finally, application support for the two possible network topologies described in the standard. This is an initial commit which describes main data structures needed for ieee802.15.4 compatible devices representation in the MAC layer.

We don't have any known kernelspace protocol which really use this feature. And I don't know an real user of this feature. We simply drop this feature now.

ieee802154: add TX power control to wpan_phy Replace the current u8 transmit_power in wpan_phy with s8 transmit_power. The u8 field contained the actual tx power and a tolerance field, which no physical radio every used. Adjust sysfs entries to keep compatibility with userspace, give tolerances of +-1dB statically there. This patch only adds support for this in the at86rf230 driver and the RF212 chip. Configuration calculation for RF212 is also somewhat basic, but does the job - the RF212 datasheet gives a large table with suggested values for combinations of TX power and page/channel, if this does not work well, we might have to copy the whole table.

Driver support for this is available in at86rf230 for the RF212 chips. Since for these chips the minimal energy detection threshold depends on page and channel used, add a field to struct at86rf230_local that stores the minimal threshold. Actual ED thresholds are configured as offsets from this value. For RF212, setting the ED threshold will not work before a channel/page has been set due to the dependency of energy detection in the chip and the actual channel/page selected.

mac802154: add interframe spacing time handling This patch adds a new interframe spacing time handling into mac802154 layer. Interframe spacing time is a time period between each transmit. This patch adds a high resolution timer into mac802154 and starts on xmit complete with corresponding interframe spacing expire time if ifs_handling is true. We make it variable because it depends if interframe spacing time is handled by transceiver or mac802154. At the timer complete function we wake the netdev queue again. This avoids new frame transmit in range of interframe spacing time. For synced driver we add no handling of interframe spacing time. This is currently a lack of support in all synced xmit drivers.

mac802154: basic ieee802.15.4 device structures The IEEE 802.15.4 Working Group focuses on the standardization of the bottom two layers of ISO/OSI protocol stack: Physical (PHY) and MAC. The MAC layer provides access control to a shared channel and reliable data delivery. The main functions performed by the MAC sublayer are: association and disassociation, security control, optional star network topology functions, such as beacon generation and Guaranteed Time Slots (GTSs) management, generation of ACK frames (if used), and, finally, application support for the two possible network topologies described in the standard. This is an initial commit which describes main data structures needed for ieee802.15.4 compatible devices representation in the MAC layer.
