There are tracking risks associated with using a fixed or static IRK.
If enabled this option, Bluedroid will assign a new randomly-generated IRK
when all pairing and bonding records are deleted. This would decrease the ability
of a previously paired peer to be used to determine whether a device
with which it previously shared an IRK is within range.
