/*
    NOTES:

    Gets, reads, receives, etc. are all even numbered functions.
    Sets, writes, sends, etc. are all odd numbered functions.
    Functions that both send and receive data can be either but an attempt is made
    to use the function number that indicates the greater transfer amount.
    Functions that do not send or receive data use odd function numbers.

    Some functions are synonyms like read, receive and send, write.

    All common functions will have a code of less than 0x80.
    Unique functions to a class will start at 0x80.
    Executive Functions start at 0xA0.

    Utility Message function codes range from 0 - 0x1f
    Base Message function codes range from 0x20 - 0xfe
    Private Message function code is 0xff.

    Detailed Status Codes for HBA operations

    Note:
    The 16-bit Detailed Status Code field for HBA operations is divided
    into two separate 8-bit fields.  The lower 8 bits are reserved.  The
    upper 8 bits are used to report Adapter Status information.	 The
    definitions for these two fields, however, will be consistent with
    the standard reply message frame structure declaration, which treats
    this as a single 16-bit field.  In addition, the values used will be
    consistent with the Adapter Status codes defined for the SCSI
    Peripheral class.  Theses codes are based on CAM-1.	 In other words,
    these definitions are a subset of the SCSI peripheral class codes.
    Where applicable, "SCSI" has been removed from the definition.
