Just think about all the things a malicious host can do on an IB fabric.
For example, a malicious SMA could send an unending stream of traps to
the SM, or consume huge SM resources by faking an ever-changing virtual
topology, or just report a GID that collides with another port on the
fabric.  And I'm sure there are other things you can think of if you try
to get really nasty.
