The Security Send command is used to transfer security protocol data
to the controller. The data structure transferred to the controller
as part of this command contains security protocol specific commands
to be performed by the controller. The data structure transferred may
also contain data or parameters associated with the security protocol
commands. Status and data that is to be returned to the host for the
security protocol commands submitted by a Security Send command are
retrieved with the Security Receive command.
The association between a Security Send command and subsequent Security
Receive command is Security Protocol field dependent as defined in SPC-4.
