I've been quite supportive of APM in the past, IMHO I think it is
something unique to IB that should be exploited as often as possible.
Improving the RDMA-CM to setup APM at all would be a great first step,
but some SM work is also ultimately needed to get sufficiently
independent/redundant paths.
I would like to see the full APM support eventually implemented - this
would be fail over across adaptor ports, where each port is on a
seperate subnet - so you get full redundancy of cabling, switching and
management software.
