What's the current plan for this RFE? There isn't an active project that depends on it, which probably allows it to be on backburner. But as usual, it might be a bit of a chicken/egg situation.
Project Brussels is migrating network drivers from driver.conf and ndd tunables to dladm-based link properties. The properties are applied when a network link is plumbed, and can also be changed on the fly via dladm(1M). It is basically what all Solaris driver configuration should be like, but network drivers need it the most and cannot wait for next-gen driver.conf to come along. Although link properties are currently stored in a file, Clearview is planning to move them to SMF. Our current prototype uses an SMF service whose only job is to receive door upcalls from the kernel and push the requested properties into the kernel - it has some boot-related issues, scales poorly and is, by and large, an architectural wart. It would be nice if we could use standard SMF interfaces from the kernel, at least in the foreseeable future. -Artem
