2013-02-06wpan: use stack buffer instead of heapAlexander Aring1-6/+1
head buffer is only temporary available in mac802154_header_create. So it's not necessary to put it on the heap. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2013-01-11net/mac802154: remove depends on CONFIG_EXPERIMENTALKees Cook1-1/+1
The CONFIG_EXPERIMENTAL config item has not carried much meaning for a while now and is almost always enabled by default. As agreed during the Linux kernel summit, remove it from any "depends on" lines in Kconfigs.

2013-01-04mac802154: fix NOHZ local_softirq_pending 08 warningAlexander Aring1-1/+1
When using nanosleep() in an userspace application we get a ratelimit warning NOHZ: local_softirq_pending 08 for 10 times. This patch replaces netif_rx() with netif_rx_ni() which has to be used from process/softirq context. The process/softirq context will be called from fakelb driver. See linux-kernel commit 481a819 for similar fix. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-12-14mac802154: fix destructon ordering for ieee802154 devicesKonstantin Khlebnikov1-2/+2
mutex_destroy() must be called before wpan_phy_free(), because it puts the last reference and frees memory. Catched as overwritten poison in kmalloc-2048.

Conflicts: drivers/net/caif/caif_hsi.c drivers/net/usb/qmi_wwan.c The qmi_wwan merge was trivial. The caif_hsi.c, on the other hand, was not. It's a conflict between 1c385f1fdf6f9c66d982802cd74349c040980b50 ("caif-hsi: Replace platform device with ops structure.") in the net-next tree and commit 39abbaef19cd0a30be93794aa4773c779c3eb1f3 ("caif-hsi: Postpone init of HIS until open()") in the net tree. I did my best with that one and will ask Sjur to check it out. Signed-off-by: David S. Miller <davem@davemloft.net>

2012-06-26mac802154: add wpan device-class supportalex.bluesman.smirnov@gmail.com6-1/+573
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.

Slaves represent typical network interfaces available from userspace. Each ieee802154 device/transceiver may have several slaves and able to be associated with several networks at the same time.
