See the man page updates that were made.  There may still be some errors 
or omissions, but I tried to address Doug's comments.

correct - there's a comment in the header file about the passive side 
ignoring this value

The passive side uses the value from the req.  The active side uses the 
value from the rep.

It's a property of the HCA, but it's not clear to me at the moment what 
a user does with this field.
