Ethdev is the only class exposing such option.
And we already have some requests to replace it with
on-demand runtime dynamic size.
That's why it's better not exposing such bad config.
Anyway we are probably not going to need more than 32 regex engines
in the near future. It gives us time to switch to a dynamic model.
