help
Use random number generation selected by the Controller.
Bluetooth Core Specification mandates a use of random number generator
compliant with FIPS PUB 140-2.
Deselecting this option allows for Controllers to use other entropy
generators which may not be true random number generators, and hence
would make the implementation experimental.
A Controller implementation could also provide custom bare-metal
random number generator implementation without any support in Zephyr
driver, i.e. there is no ENTROPY_HAS_DRIVER enabled.

help
Use random number generation and AES encryption support functions
provided by the controller.
Support for HCI LE Rand and HCI LE Encrypt commands is mandatory by
Bluetooth Core Specification.
In an Application/Host and Controller split (using a HCI transport) or
combined builds for single CPU SoCs, applications can use their own
FIPS-197 compliant cryptographic implementations. In this case the
Controller cryptographic implementations can be disabled to save flash

the number of RX nodes prepared in one ISO event for each
active ISO group. This depends on the number of bursts in an
ISO group and number of groups, and may need to be set lower
that the theoretical maximum. Default of 8 is for supporting
two groups of 4 payloads, e.g. 2 CIGs with 2 CISes of BN=2.
