* Description:
|
||||
* This function is called in the following scenarios:
|
||||
* - The MAC receives a START.request primitive
|
||||
* - Upon receiving the IEEE802154_SFEVENT_ENDOFACTIVE event from the
|
||||
* radio layer, the MAC checks the bf_update flag and if set calls this
|
||||
* function. The bf_update flag is set when various attributes that
|
||||
* effect the beacon are updated.
|
||||
*
|
||||
* Internal function used by various parts of the MAC layer. This function
|
||||
* uses the various MAC attributes to update the beacon frame. It loads the
|
||||
* inactive beacon frame structure and then notifies the radio layer of the
|
||||
* new frame. the provided tx descriptor in the indirect list and manages the
|
||||
* scheduling for purging the transaction if it does not get extracted in
|
||||
* time.
|
||||
*
|
||||
* Assumptions:
|
||||
* Called with the MAC locked
