menuconfig WIRELESS_IEEE802154
bool "IEEE 802.15.4 Support"
default n
select MM_IOB
depends on WIRELESS
---help---
Enables a Media Access Controller for any IEEE802.15.4 radio
device. This in turn can be used by higher layer entities
such as 6lowpan.

config IEEE802154_MAC_DEV
bool "Character driver for IEEE 802.15.4 MAC layer"

depends on WIRELESS_IEEE802154
---help---
Enable the device driver to expose the IEEE 802.15.4 MAC layer
access to user space as IOCTLs

---help---
Work queue support is required to use the IEEE 802.15.4 MAC layer.
If the low priority work queue is available, then it should be used by
the driver.

int "Number or TX descriptors"
default 3
---help---
Configured number of Tx descriptors. Default: 3
config IEEE802154_IND_PREALLOC
int "Number of pre-allocated meta-data structures"
default 20
---help---
This specifies the total number of preallocated meta data structures
must be allocated with each incoming packet. These may be allocated
from either from tasking logic or from interrupt level logic.
config IEEE802154_IND_IRQRESERVE
int "Rserved pre-allocated meta-data structures"
default 10
---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.

Work queue support is required to use the IEEE802.15.4 network
