Just for the record it is controlling the build of both ib_addr and
rdma_cm modules where rdma address resolution is a part from the overall
rdma communication management managed by the rdma_cm module.
Anyway, if you prefer to leave the config name as is, let it be.

I think i got it (at last) if INFINIBAND is selected it causes the
selection of INFINIBAND_ADDR_TRANS as long as INET is selected so if
something (eg iSER) is dependent on INFINIBAND and INET make rndconfig
would do the job of selecting both of them when it selects iSER, correct?
