The name is very generic, could you rename the structure to something
like vpp_cycles_data?

please check your editor, those fields should have a tab to the right.

I cannot see how this 'freq' structure field is used? I can see that you
fill it in 3/5 patch but you don't used nowhere.

Having the fact that freq field seems not needed can we just merge the
fields in venus_inst structure?
