one of the first checks in the swfilter code will discard them. If you

Every accepted packet is tested twice.
Discarded packets are tested once (and very early).
So we gain here and loose there.
In relation to "one of the first checks", do you think that the swfilter
code is fast enough to let us just open_whole_bandwith when we're out of
hw filters?
sure, why not? All other decoder-less PCI cards wotk reliably the same
way...
