the driver.

WARNING!! The IEEE802.15.4 network device must never run on the same

|
work queue as does the IEEE 802.15.4 MAC. That configuration will

|
cause deadlocks: The network logic may be blocked on the work queue
|
|
waiting on resources that can only be freed by the MAC logic but the
|
|
MAC is unable to run because the work queue is blocked. The

recommended configuration is: Network on the LP work queue; MAC on HP

work queue. Blocking on the HP work queue is a very bad thing in

any case.

|

Configured number of Tx descriptors. Default: 3
|
|
|
|
When used with 6LoWPAN, the descriptor allocator runs on a work
|
|
and must avoid blocking if possible. Each frame will be provided in
|
|
an IOB and each TX frame will need a TX descriptor. So the safe
|
|
thing to do is set CONFIG_MAC802154_NTXDESC to CONFIG_IOB_NBUFFERS.
|
|
Then there should be the maximum pre-allocated buffers for each
|
|
possible TX frame.

When various MAC management events occur, the MAC notifies the registered

events are primitives such as Association Indication etc.

information for all unique beacons received. This is the number of unique

descriptors that can be held before the scan cancels with LIMIT_REACHED.

|

---help---
|
|
If meta-data structures can be allocated from interrupt handlers,
|
|
then this specifies the number of pre-allocatd meta-data structures
|
|
that are reserved for for use only by interrupt handlers. This may
|
|
be zero to reserve no meta-data structures for interrupt handlers.
|
|
In that case, the allocation will fail if tasking logic has
|
|
allocated them all.
|
|
|
|
Interrupt logic will first attempt to allocate from the general,
|
|
pre-allocated structure pool that will contain up to (size
|
|
CONFIG_IEEE802154_IND_PREALLOC - CONFIG_IEEE802154_IND_IRQRESERVE)
|
|
entries. If that fails, then it will try to take a structure from
|
|
the reserve (size CONFIG_IEEE802154_IND_IRQRESERVE).
|
|
|
|
Non-interrupt logic will also first attempt to allocate from the
|
|
general, pre-allocated structure pool. If that fails, it will
|
|
dynamically allocate the meta data structure with an additional cost
|
|
in performance.
|
|
|
|
NOTE: Currently marked as experimental and with a default of zero
|
|
because there are no interrupt level allocations performed by the
|
|
current IEEE 802.15.4 MAC code.

An example case would be when 6LoWPAN and the MAC character driver are

enabled. Both have receivers registered with the MAC. The 6LoWPAN layer

should get assigned a higher priority than the character driver. In this

case, the 6LoWPAN receiver will receive the frame first. If the frame is

a 6LoWPAN frame, it will claim the frame and the MAC will not pass the

MAC layer will call the next highest priority receiver, in this case,
