The address of the packet is passed as an argument to the routine.
This packet contains the memory address (pointer) of the
conÞguration parameters to/with you wish to update/change. The
packet also contains a control ßag Þeld; this control ßag speciÞes
the conÞguration operation: read, write, or write to NVRAM. All
packets must be word-aligned. The format for the packet structure,
NIOTCALL, is shown below:
