To understand multidata or the meta data? Yes, a module
needs to understand multidata in order to use it. It
is based on mblk_t, so if a module does not understand this
new type, it will just drop it. It won't panic :-)
But for the meta data (attribute), not all modules need to
understand all the attributes. Only when a module needs
to know about certain attributes, it will check them. The
other attributes are not visible.
