Hi Vernon,

There were a few earlier posts about what Kumar is trying to accomplish.
We have a server with 1 chassis and 4 hosts.  Each host card has on it a
micro-controller which talks IPMB to the BMC.  My understanding is that
Kumar is trying to reuse most of the providers by taking the IPMB
message, stripping off a header, and then reusing the existing IPMI
provider for handling the bulk of the message.
