I had a closer look at this some time ago and noticed a couple of bugs
(f.i. double buffering might be enabled or disabled or the buffers
switched while a packet is queued, so on dequeue the wrong buffer will
have its queue length decremented) and also found the hashing quite
inefficient, so I've implemented my own version. There's still a minor
bug somewhere, but if people are interested I could finish it some
time soon and post the patches.
