extend ipmi enumerator module to enumerate a node for the service processor
It would be useful to extend the ipmi topo enumerator to enumerate the service processor (SP), if present, as a child of the "motherboard" node. It should include properties to expose the network configuration of the SP as well as the current firmware version. It should also include any available FRU identity information for the SP in the authority portion of its FMRI.
Note, this change has already been integrated into illumos-joyent as part of the larger commit linked below:
