/* L1 Target Addresses */
/*
 * L1 commands and responses use source/target addresses that are
 * 32 bits long.  These are broken up into multiple bitfields that
 * specify the type of the target controller (could actually be L2
 * L3, not just L1), the rack and bay of the target, and the task
 * id (L1 functionality is divided into several independent "tasks"
 * that can each receive command requests and transmit responses)
