Maximum size of each HCI event buffer. E.g. one big event
for LE is the Command Complete for Read Local Supported
Commands. It is a 3 byte Command Complete header + 65 byte
return parameters = 68 bytes in total.

Size of the receiving fiber stack. This is the context from
which all event callbacks to the application occur. The
default value is sufficient for basic operation, but if the
application needs to do advanced things in its callbacks that
require extra stack space, this value can be increased to
accomodate for that.

This option places Security Manager in a Debug Mode. In this mode
predefined Diffie-Hellman private/public key pair is used as described
in Core Specification Vol. 3, Part H, 2.3.5.6.1. This option should
only be enabled for debugging and should never be used in production.
If this option is enabled anyone is able to decipher encrypted air
traffic.
