No need to trigger it, faking it would be enough, e.g.:

+ if (++i < 3) + skb = dev_alloc_skb(frag_length + 4); + else + skb = NULL;

Don't bet on this triggering on a real system without some additional scaffolding - take a look at what the function is doing, and ask yourself how many times it will be called on the average system :)
