Other than the fact that it doesn't make much sense without RDMA
interfaces, it doesn't have to depend on the rdma.service.  However, in
the early days, that wasn't true, it had problems if it was started
before all interfaces were up.  Back in the day, I put that dependency
in there to help alleviate that issue.  I haven't tested it lately to
see if it's gone or not, but one would hope so.  However, at least in
the systemd world, the rdma service is autostarted, so ibacm probably
ought to be autostarted too, regardless of whether it depends on the
rdma service or not.
