2015-05-23mac802154: remove mib lockAlexander Aring
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.

2015-05-23mac802154: use atomic ops for sequence incrementationAlexander Aring
This patch will use atomic operations for sequence number incrementation while MAC header generation. 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.

2015-05-23mac802154: remove pib lockAlexander Aring
This patch removes the pib lock which is now replaced by rtnl lock. The new interface already use the rtnl lock only. Nevertheless this patch will fix issues while using new and old interface at the same time.

2014-11-09mac802154: move mac pib attributes into wpan_devAlexander Aring
This patch moves all mac pib attributes into the wpan_dev struct. Furthermore we can easier access these attributes over the netdev 802154_ptr pointer. Currently this is only possible over a complicated callback structure in mac802154 because subif data structure is accessable inside mac802154 only.

2014-11-02mac802154: set panid address filter on ifupAlexander Aring
This patch moves the setting of hardware panid address filtering inside of interface up instead doing it it directly inside of netlink interface. The netlink call which can only be called when netif isn't running sets only the necessary panid value in sdata. After an interface up the address filter will be set with this value.

This patch moves the setting of hardware short address filtering inside of interface up instead doing it it directly inside of netlink interface.

This patch moves the setting of hardware extended address filtering inside of interface up instead doing it directly inside of netlink interface.

Use the operations on 802.15.4 header structs introduced in a previous patch to create and parse all headers in the mac802154 stack. This patch reduces code duplication between different parts of the mac802154 stack that needed information from headers, and also fixes a few bugs that seem to have gone unnoticed until now: * 802.15.4 dgram sockets would return a slightly incorrect value for the SIOCINQ ioctl * mac802154 would not drop frames with the "security enabled" bit set, even though it does not support security, in violation of the standard Signed-off-by: Phoebe Buckheister <phoebe.buckheister@itwm.fraunhofer.de> Signed-off-by: David S.
