142 Gets, reads, receives, etc. are all even numbered functions.
143 Sets, writes, sends, etc. are all odd numbered functions.
144 Functions that both send and receive data can be either but an attempt is made
145 to use the function number that indicates the greater transfer amount.
146 Functions that do not send or receive data use odd function numbers.
148 Some functions are synonyms like read, receive and send, write.
150 All common functions will have a code of less than 0x80.
151 Unique functions to a class will start at 0x80.
152 Executive Functions start at 0xA0.
154 Utility Message function codes range from 0 - 0x1f
155 Base Message function codes range from 0x20 - 0xfe
156 Private Message function code is 0xff.
164 SCSI Peripheral Class specific functions
166 Although the names are SCSI Peripheral class specific, the values
167 assigned are common with other classes when applicable.

175 Detailed Status Codes for SCSI operations
177 The 16-bit Detailed Status Code field for SCSI operations is divided
178 into two separate 8-bit fields. The lower 8 bits are used to report
179 Device Status information. The upper 8 bits are used to report
180 Adapter Status information. The definitions for these two fields,
181 however, will be consistent with the standard reply message frame
182 structure declaration, which treats this as a single 16-bit field.
