I don't buy this.  The only thing making this config option visible
does is make it more likely (far more likely) that someone will
disable it.  Right now the RDMA CM is built as long as INFINIBAND and
INET are enabled.  No one is going to turn off INET on any normal
system so effectively the RDMA CM is always built whenever INFINIBAND
is enabled.

As far as making a config symbol to depend on, I think INET makes as
much sense or more: something using IP addressing naturally depends on
having IP networking.
