---help---
|
|
This specifies the total number of preallocated primitive structures.
|
|
A primitive is an abstracted data type that provides service information
|
|
between the MAC layer and the next highest layer. These may be allocated
|
|
from either from tasking logic or from interrupt level logic.

int "Reserved pre-allocated primitive structures"
|
|
default 0

depends on EXPERIMENTAL
|
|
---help---
|
|
If primitives can be allocated from interrupt handlers, then this
|
|
specifies the number of pre-allocated 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_PRIMITIVE_PREALLOC - CONFIG_IEEE802154_PRIMITIVE_IRQRESERVE)
|
|
entries. If that fails, then it will try to take a structure from
|
|
the reserve (size CONFIG_IEEE802154_PRIMITIVE_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 primitive 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.

|

There are two types of IEEE 802.15.4 radios supported. Those that provide
|
|
all MAC functionality equivalent to the MAC802154 software implementation,
|
|
and radios that provide a lower half to the MAC802154 software layer.
|
|
This option enables the software MAC layer that can interface with
|
|
the lower-half radio drivers.

---help---
|
|
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.

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

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

When the MAC layer receives an incoming data frame, it passes the frame
|
|
to registered receivers, in order of receiver priority, until one of the
|
|
receivers claim the frame.
|
|
|
|
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
|
|
frame to any additional receivers. If it does not claim the frame, the
|
|
MAC layer will call the next highest priority receiver, in this case,
|
|
the MAC character driver (which should always be lowest priority since
|
|
it is a "catch-all" type receiver).
