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 :)
Seems to be called a lot.
Oh? Explain to us what this function is actually doing, in general terms, and then give us a rough estimate of how many times per boot it's called.
