I definitely think that allowing the flexibility to configure ports individually
is required.  It's easy to imagine a case with a separate front-end and
back-end networks on the two HCA ports (this would be a pretty normal
ethernet config), where only one port should be a target port.

It may not be how people do things now but it should at least be possible.
