This looks like a completely API burden?

netfilter xt targets are not really compatible with netsched action.
I've got to say, the patch is just a way to make checkentry return
false and avoid panic. like [1] said

I don't doubt you fix a crash, I am thinking if we can
"fix" the API instead of fixing the caller.

I am not familiar with this API, so just my 2 cents...
