connect_req net charge is as follows:

Whether the Inita (initiator Address) field is public (txadd=0) or random (txadd=1) is determined by the Txadd domain in the net payload.

Whether the Adva (Advertiser Address) field is public (rxadd=0) or random (rxadd=1) is determined by the Rxadd domain in the net payload.
