Looks like your configuration is ok.

The debug message prints the dest GID on return which is a little 
misleading since the route information is not updated until the async 
callback fires. I will change this to print the src and dst ip addresses.

What address are you using for dap_ep_connect? The src_ip address will 
be set to 10.10.10.12 which was retrieved from the hca_open and the 
dst_ip address is taken from your (struct sockaddr_in *) 
remote_ia_address provided with your dat_ep_connect call.  Did you 
ifconfig the IPoIB devices on both sides?  Can you ping using the IPoIB 
addresses?
