> Instead of checking the gen number every time we need to know the max
> number of entries, just save it into the table struct so we don't need
> extra branches throughout the code. This will be useful for Ice Lake
> that has 64 rather than 62 defined entries. Ice Lake changes will be
> added in a follow up.
> 
> v2: make size and n_entries `unsigned int` and introduce changes as a
>     pre-work for the Ice Lake changes (Tvrtko)
