I still prefer the destid as the single identification id.

In your patch you allocate individual destid for switches. This method
has two problems:
1. The destid for the switch needs an additional mechanism to share it
among processors in the RIO network,

? See comment for 2)

2. It takes ID value away from the pool of available IDs, what will

It does not take an ID away, it shares it with a connected endpoint to 
that switch. The tag uses one extra bit to identify the device as a 
switch instead of an endpoint. This provides the information to 
unambiguously identify a switch from an endpoint.
