Hi, I had a question about Linux routing functions, suppose I want to find out what interface does a route to an IP address belong to - is it better (in terms of performance) to use ip_route_output_key or fib_lookup. My initial guess from looking at the source code is fib_lookup since the routing cache wont be helpful since I wont have any interface information (rather want to find out interface information) but wanted to be sure.
