+ * Place-holder for FDs, we represent it via the simplest form that we need for

+ * is impractical to define One True Struct, because the resulting encoding
+ * routines (lots of read-modify-writes) would be worst-case performance whether
+ * or not circumstances required them.)
+ *
+ * Note, as with all data-structures exchanged between software and hardware (be
+ * they located in the portal register map or DMA'd to and from main-memory),
+ * 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
+ * contained within this structure are represented in host-endianness, even if
+ * 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
+ * sequence of bytes 0xfe, 0xed, 0xab, and 0xba. So "frc" should be the 32-bit
+ * 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;
