ScanResultList_t	Union	In order to allow proper alignment of members of the PAN descriptor list in the scan confirm for non 8-bit platforms (such as ARM), the variable portion of the scan confirm at the end of the primitive needs to be aligned to at least the size of WPAN_Pandescriptor_t. This has no impact for 8-bit platforms.
