Maybe I wasn't being clear.  If the user tries to connect from 127.0.0.1 to 
192.168.0.101, this patch will change their source address from 127.0.0.1 to be 
192.168.0.101.  The current code leaves the source address as 127.0.0.1.

What ib_addr is trying to allow is connecting to a remote IP address.  If a 
source address is not specified, then one is assigned.
