There are at least three viable ways of doing this that don't involve
duplicating code:
- integrate your driver into ON, so that you're shipping in the same
consolidation as this Consolidation Private interface;
- negotiate with the owners of the interface (start with
networking-discuss) to have the stability level raised, perhaps
making it part of the DDI, so that you can use it without trouble;
or
- get an ARC contract on the interface so that the underlying
interface can't be changed without coordinating with you.
In Solaris (and indeed across Sun), we intentionally separate the
world into "public" and "private" interfaces. The former are
documented and can change only in certain documented ways. The latter
are undocumented and may change without warning.
"Private" here doesn't mean "secret." It merely means "not
documented."
We do this intentionally to avoid the sorts of versioning madness that
afflicts some other software systems. The underlying idea is simple:
every project must explain what parts they expect others to use (their
"exported interfaces") and what things they're using that are defined
by others (their "imported interfaces"), and the ARC connects these
up. You're not allowed to use things from other projects in ways that
are contrary to what that other project specified.
