It works just fine. First test used the wrong VM and was puzzled to not 
see the table id in the output. Then I realized the older kernel did not 
recognize the RTM_F_LOOKUP_TABLE; silently ignores the flag. With a 
kernel that does recognize it I get the table id in the output when it 
is not main.
