Why has that change been implemented ? As far as I know InfiniBand
HCAs have either one or two ports. If there are two ports present, at
most one is active at any time. I don't see the point of making
individual ports visible and configurable in configfs on the target
instead of the HCA. If a user enables one port of a HCA but not the
other, that could result in some really strange and hard to diagnose
failures if the IB subnet manager decides to switch over to the other
port. Or am I missing something ?

Bart.
