I have actually read that pdf :)
I saw a couple of typos, i might have missed others:
page 8 in that pdf file, line 6 from the bottom:
"the packet that will then be allocated later when the packet is dropped"
shouldn't this say "be deallocated" instead of "be allocated" ?
page 10, line 3 from the top:
"it is not possible to list stored filters bwing them stored"
what was "bwing" supposed to mean ?
