Did you have something specific in mind?

ucma_set_ib_paths should be able to accommodate this; we just need some rules
defined. More invasive kernel changes are needed to do anything with the extra
paths.

For APM, I'm guessing that you'd like a way to set a new alternate path after
establishing a connection. ucma_set_ib_paths could still do this based on the
state of the connection.
