GTP: convert from translation port to dual faced port
I spent numerous hours in trying to avoid the dual faced port from
segfaulting, but in the end didn't succeed :(
The easy way was then simply to fall back to the known-working pattern
of the dual-faced port, which I already successfully used also on the NS
module for the Gb Inteface
