2013-10-306lowpan: set and use mac_len for mac header lengthAlexander Aring1-0/+2
Set the mac header length while creating the 802.15.4 mac header. Drop the function for recalculate mac header length in upper layers which was static and works for intra pan communication only.

2013-04-07mac802154: Increase tx_buffer_lenAlan Ott1-1/+1
Increase the buffer length from 10 to 300 packets. Consider that traffic on mac802154 devices will often be 6LoWPAN, and a full-length (1280 octet) IPv6 packet will fragment into 15 6LoWPAN fragments (because the MTU of IEEE 802.15.4 is 127). A 300-packet queue is really 20 full-length IPv6 packets. With a queue length of 10, an entire IPv6 packet was unable to get queued at one time, causing fragments to be dropped, and making reassembly impossible.

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>

2013-01-04mac802154: 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>

2012-06-26mac802154: add wpan device-class supportalex.bluesman.smirnov@gmail.com1-0/+559
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.
