Watching For Interfaces
When your code comes up, the IPMI driver may or may not have detected
if IPMI devices exist. So you might have to defer your setup until
the device is detected, or you might be able to do it immediately.
To handle this, and to allow for discovery, you register an SMI
watcher with ipmi_smi_watcher_register() to iterate over interfaces
and tell you when they come and go.
