+ *
+ * Note, as with all data-structures exchanged between software and hardware (be

+ * the driver ensures that the caller of the driver API sees the data-structures
+ * in host-endianness. "struct qbman_fd" is no exception. The 32-bit words

+ * hardware always treats them as little-endian. As such, if any of these fields
+ * are interpreted in a binary (rather than numerical) fashion by hardware
+ * blocks (eg. accelerators), then the user should be careful. We illustrate
+ * with an example;
+ *
+ * Suppose the desired behaviour of an accelerator is controlled by the "frc"
+ * field of the FDs that are sent to it. Suppose also that the behaviour desired
+ * by the user corresponds to an "frc" value which is expressed as the literal

+ * value in which 0xfe is the first byte and 0xba is the last byte, and as
+ * hardware is little-endian, this amounts to a 32-bit "value" of 0xbaabedfe. If
+ * the software is little-endian also, this can simply be achieved by setting
+ * frc=0xbaabedfe. On the other hand, if software is big-endian, it should set
+ * frc=0xfeedabba! The best away of avoiding trouble with this sort of thing is
+ * to treat the 32-bit words as numerical values, in which the offset of a field
+ * from the beginning of the first byte (as required or generated by hardware)
+ * is numerically encoded by a left-shift (ie. by raising the field to a
+ * corresponding power of 2). Ie. in the current example, software could set
+ * "frc" in the following way, and it would work correctly on both little-endian
+ * and big-endian operation;
