Enable support for raw, IEEE 802.15.4 sockets.
|
|
|
|
Raw sockets allow receiving and transmitting IEEE 802.15.4 radio
|
|
frames without a layer2 protocol such as 6LoWPAN in between. Frames
|
|
received are copied into a IEEE 802.15.4 socket tap before they
|
|
enter the network. Frames written into a IEEE 802.15.4 socket will
|
|
bypass the network altogether and will be sent directly to the
|
|
IEEE 802.15.4 MAC network interface driver outgoing frame queue.

For standard IEEE 802.15.4 radios, this should always be 127 bytes.
|
|
However, some IEEE 802.15.4 radios may non-standard frame lengths.

This setting is currently used only for detection data transfers

that would exceed the radio frame length.

---help---
|
|
As frames are received, then are help in an RX queue. They remain
|
|
in the RX queue until application logic reads the queue frames. To
|
|
prevent overrun, the maximum backlog may be set to a nonzero value.
|
|
What the backlog of queue frames reaches that count, the olds frame
|
|
will be freed, preventing overrun at the cost of losing the oldest
|
|
frames.
|
|
|
|
NOTE: The special value of zero will disable all backlog checkes.
