/*
* This packet-construction scheme makes the following assumptions:
*
* 1. The compiler is able to generate code which addresses one- and two-byte
* quantities. In the worst case, this would be done with bit-fields. If
* bit-fields are used it may be necessary to reorder the request fields in
* this file, depending on the order in which the machine assigns bit fields
* to machine words. There may also be a problem with sign extension, as K+R
* specify that bitfields are always unsigned.
*
* 2. 2- and 4-byte fields in packet structures must be ordered by hand such
* that they are naturally-aligned, so that no compiler will ever insert
* padding bytes.
*
* 3. All packets are hand-padded to a multiple of 4 bytes, for the same reason.
