*
* See rdc.h for description of entity_index
* Shifts and masks help get only the bits in question to decode/encode
*
* Ex, RDC_ENTITY_TYPE_SHIFT = 29 helps shift the 29 irrelevant bits, so we're
* only left with the top 3 type bits.
* Then, the corresponding 3 type bits are anded with the RDC_ENTITY_TYPE_MASK = 0x7
* which = 111 in binary, "copying" the type bits.
