| | | | | | | | | | | mac802154_mlme_start_req() calls ieee802154_mlme_ops(dev)->llsec->set_params() on the net_device passed into it, however, this net_device will always be a mac802154 net_device, so just call mac802154_set_params() directly instead.

* mac802154: remove mib lockAlexander Aring2015-05-231-4/+2
| | | | | | | | | | | | | | | This patch removes the mib lock. The new locking mechanism is to protect the mib values with the rtnl lock. Note that this isn't always necessary if we have an interface up the most mib values are readonly (e.g. address settings). With this behaviour we can remove locking in hotpath like frame parsing completely. It depends on context if we need to hold the rtnl lock or not, this makes the callbacks of ieee802154_mlme_ops unnecessary because these callbacks hols always the locks.

Upper layers like af_802154 or 6LoWPAN could call this function in a parallel context while generating 802.15.4 MAC header before queuing into wpan interfaces transmit queue.

* cfg802154: introduce wpan phy flagsAlexander Aring2015-05-191-3/+3
| | | | | | | | | | | | | | | | | | | | | | | This patch introduce a flag property for the wpan phy structure. The current flag settings in ieee802154_hw are accessable in mac802154 layer only which is okay for flags which indicates MAC handling which are done by phy. For real PHY layer settings like cca mode, transmit power, cca energy detection level. The difference between these flags are that the MAC handling flags are only handled in mac802154/HardMac layer e.g. on an interface up. The phy settings are direct netlink calls from nl802154 into the driver layer and the nl802154 need to have a chance to check if the driver supports this handling before sending to the next layer. We also check now on PHY flags while dumping and setting pib attributes. In comparing with MIB attributes the 802.15.4 gives us an default value which we assume when a transceiver implement less functionality. In case of MIB settings the nl802154 layer doesn't need to check on the ieee802154_hw flags then.

* ieee802154: rework cca settingAlexander Aring2014-12-191-3/+3
| | | | | | | | | | 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: move phy settings into netlink receiveAlexander Aring2014-11-021-0/+21
| | | | | | | | | | | | All PHY attributes should be directly set to the transceiver after netlink. MAC attributes should be set by interface up. Currently the macparams netlink cmd contains mixed attributes of phy and mac settings. This patch moves all phy settings to the netlink receive function for setting macparams. This is the only way which doesn't change the userspace API and keep the deprecated netlink interface alive.
