In 4.6.4, the standard states that "The ECR routes messages ...  Enough routing 
resources shall be provided to support at least one connection."

What should be the expander's response when it is has no more routing resources
 (ie, the expander finds a matching destination port that supports the requested 
connection rate and none of those phys are returning Phy Status (Connection))?
 
I don't believe the standard defines the expected behavior.

Thanks,
Gil
