2014-11-05mac802154: move interface del handling in ifaceAlexander Aring4-18/+16
This patch moves and rename the mac802154_del_iface function into iface.c and rename the function to ieee802154_if_remove which is a similar naming convention like mac80211. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2014-11-05ieee802154: remove nl802154 unused functionsAlexander Aring1-6/+0
The include/net/nl802154.h file contains a lot of prototypes which are not used inside of ieee802154 subsystem. This patch removes this file and make the only one used prototype "ieee802154_nl_start_confirm" as static declaration in ieee802154/nl-mac.c Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2014-11-02ieee802154: remove unnecessary functionsAlexander Aring1-22/+0
This patch fixes commit c7420c367d63a7e1414e010afb52c3837fd9134e ("mac802154: move mac_params functions into mac_cmd"). The mac_params functions wasn't deleted by this commit.

2014-11-02mac802154: cfg: add missing includeAlexander Aring1-0/+1
Running make C=2 occurs warning: symbol 'mac802154_config_ops' was not declared. Should it be static? This patch adds a missing include in cfg.c to solve this warning.

This patch use the validation function to check if an extended address is valid or not while set the extended address. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2014-11-02mac802154: move phy settings into netlink receiveAlexander Aring2-19/+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.

2014-11-02mac802154: set panid address filter on ifupAlexander Aring2-51/+4
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.

2014-11-02mac802154: set short address filter on ifupAlexander Aring2-6/+4
This patch moves the setting of hardware short 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 short_addr value in sdata. After an interface up the address filter will be set with this value.

2014-11-02mac802154: set extended address filter on ifupAlexander Aring4-17/+9
This patch moves the setting of hardware extended address filtering inside of interface up instead doing it directly inside of netlink interface. Also we don't need to set the sdata extended attribute in netlink. This is already done by ndo_set_mac_address of net_device_ops.

2014-11-02cfg802154: convert deprecated iface add and delAlexander Aring3-6/+23
This patch removes the wpan_phy callbacks for add and del an interface on a phy. Instead we introduce deprecated cfg802154 callbacks for this. Furthermore we introduce a new netlink interface nl802154 which use different callbacks. The deprecated function is to have a backwards compatibility with the current netlink interface.

2014-11-02cfg802154: introduce cfg802154_registered_deviceAlexander Aring1-1/+1
This patch introduce the cfg802154_registered_device struct. Like cfg80211_registered_device in wireless this should contain similar functionality for cfg802154. This patch should not change any behaviour. We just adds cfg802154_registered_device as container for wpan_phy struct.

2014-10-29mac802154: rx: use netif_receive_skbAlexander Aring1-1/+1
This patch removes netif_rx_ni call. Instead we call netif_receive_skb, we can do that since commit c5c47e67bcd24638a059b1b5e9ec18c95f8634ca ("mac802154: rx: use tasklet instead workqueue"). Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2014-10-29mac802154: rx: remove override pkt_type set to PACKET_HOSTAlexander Aring1-1/+0

2014-10-29mac802154: rx: simplify crc receive handlingAlexander Aring1-22/+12
This patch change the actual crc handling while receive. Currently the IEEE802154_HW_RX_OMIT_CKSUM flag is used to filter a frame with a bad crc. This patch changes the behaviour of IEEE802154_HW_RX_OMIT_CKSUM to add a crc while receiving for the monitor interface. After monitor receiving we remove the crc for frame parsing. This affect the driver layer because all drivers sets IEEE802154_HW_RX_OMIT_CKSUM and deliver without checksum.

2014-10-29mac802154: separate omit tx/rx flagsAlexander Aring2-2/+2
This patch splits the IEEE802154_HW_OMIT_CKSUM hardware flag into IEEE802154_HW_TX_OMIT_CKSUM and IEEE802154_HW_RX_OMIT_CKSUM. This is useful to deliver the received crc from the driver layer to the monitor interface. At the moment we can't do that without change the xmit handling. The received checksum should be visible in monitor mode only. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

2014-10-28mac802154: add synchronization handlingAlexander Aring1-0/+7
This patch adds synchronization handling in start and stop driver ops calls. This patch is mostly grab from mac80211 which was introduced by commit ea77f12f2cc0f31168f2e0259e65a22202ac4dc2 ("mac80211: remove tasklet enable/disable").

2014-10-28mac802154: move local started handlingAlexander Aring3-26/+4
This patch removes the current handling of started boolean. This is actually dead code, because mac802154_netdev_register can't never be called before ieee802154_register_hw. This means that local->started is always be true when mac802154_netdev_register is called. Instead we using this now like mac80211 to indicate that an instance of sdata is running.

2014-10-28mac802154: rework sdata state change to runningAlexander Aring2-8/+16
This patch reworks the handling for setting the state like mac80211. We use bit's instead a bool variable. The mutex is not needed because it use test and set bits which are atomic operations. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2014-10-28mac802154: remove driver ops in wpan-phyAlexander Aring2-91/+6

2014-10-28mac802154: introduce driver-ops headerAlexander Aring1-0/+202
This patch introduce a driver-ops header file with function wrappers to call the driver ops. These wrappers checking on right context information and warn if optional driver ops are called when these aren't implemented. This behaviour is like mac80211 driver-ops header file, just without function tracing calls. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2014-10-28mac802154: declare struct ieee802154_ops as constAlexander Aring2-2/+2

2014-10-27mac802154: rx: rename remove mac802154_subif_rxAlexander Aring1-9/+3
This patch removes the mac802154_subif_rx function and do the necessary calls inside of ieee802154_rx function. The ieee802154_rx is small enough to move the functionality inside this function.

2014-10-27mac802154: tx: remove monitor receive while xmitAlexander Aring3-4/+2
This removes the call of monitor receive funktion when any interface type call xmit. There exist no such use case that a monitor interface should receive the actual sending frame. One use case could be that a wpan interface and monitor interface could be running at the same time on one phy. Then the monitor interface receives the wpan frames also. Furthermore we adding support for promiscous mode setting. With promiscous mode setting we can't run a wpan and monitor interface at the same time.

2014-10-27mac802154: rx: use tasklet instead workqueueAlexander Aring4-41/+46
Tasklets have much less overhead than workqueues. This patch also removes the heap allocation for the worker on receiving path. Like mac80211 we should prefer use a tasklet here instead a workqueue to getting fast out of interrupt context when ieee802154_rx_irqsafe is called by driver. Like wireless inside the tasklet context we should call netif_receive_skb instead netif_rx_ni anymore.
