Given a path record query for:

SGID - local
DGID - remote

What would be the SLID and DLID?

And if the query is reversed, such that:

SGID - remote
DGID - local

Are the SLID/DLID values simply reversed?

What if the DGID in the second case were a multicast GID?  What does the SLID 
become in this case?
