The stub need not use any particular size or alignment when gathering
data from memory for the response; even if @var{addr} is word-aligned
and @var{length} is a multiple of the word size, the stub is free to
use byte accesses, or not. For this reason, this packet may not be
suitable for accessing memory-mapped I/O devices.
