ieee802154: move wpan-phy.h to cfg802154.h

2014-10-25T19:39:56Z

The wpan-phy header contains the wpan_phy struct information. Later this header will be have similar function like cfg80211 header. The cfg80211 header contains the wiphy struct which is identically the wpan_phy struct inside 802.15.4 subsystem. Signed-off-by: Alexander Aring Cc: Alan Ott Signed-off-by: Marcel Holtmann

ieee802154: add netlink APIs for smartMAC configuration

2014-02-17T21:42:39Z

Introduce new netlink attributes for SET_PHY_ATTRS: * CSMA minimal backoff exponent * CSMA maximal backoff exponent * CSMA retry limit * frame retransmission limit The CSMA attributes shall correspond to minBE, maxBE and maxCSMABackoffs of 802.15.4, respectively. The frame retransmission shall correspond to maxFrameRetries of 802.15.4, unless given as -1: then the old behaviour of the stack shall apply. For RF2xy, the old behaviour is to not do channel sensing at all and simply send *right now*, which is not intended behaviour for most applications and actually prohibited for some channel/page combinations. For all values except frame retransmission limit, the defaults of 802.15.4 apply. Frame retransmission limits are set to -1 to indicate backward-compatible behaviour.

ieee802154: add support for setting CCA energy detection levels

2014-02-17T21:42:38Z

Since three of the four clear channel assesment modes make use of energy detection, provide an API to set the energy detection threshold. 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.

ieee802154: add support for CCA mode in wpan phys

2014-02-17T21:42:38Z

The standard describes four modes of clear channel assesment: "energy above threshold", "carrier found", and the logical and/or of these two. Support for CCA mode setting is included in the at86rf230 driver, predicated for RF212 chips. Signed-off-by: Phoebe Buckheister Signed-off-by: David S. Miller

ieee802154: add support for listen-before-talk in wpan_phy

2014-02-17T21:42:38Z

Listen-before-talk is an alternative to CSMA in uncoordinated networks and prescribed by european regulations if one wants to have a device with radio duty cycles above 10% (or less in some bands). Add a phy property to enable/disable LBT in the phy, including support in the at86rf230 driver for RF212 chips. Signed-off-by: Phoebe Buckheister Signed-off-by: David S. Miller

ieee802154: add TX power control to wpan_phy

2014-02-17T21:42:38Z

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.

mac802154: monitor device support

2012-05-16T19:17:08Z

Support for monitor device intended to capture all the network activity. This interface could be used by networks sniffers and is already supported by WireShark. That's a good test point to check that basic MAC support works. Signed-off-by: Alexander Smirnov Signed-off-by: David S. Miller
