Is pfil zero copy or one copy by default? If the driver supports it, does a packet get directly DMA'd in mbufs and passed over the pf which then drops the packet if applicable?BTW: You may be better off using pfil_hooks instead of netgraph for your tool. You'll save one m_copym and m_freem for each packet.
Also, did the locking work for network stack in 5.3 make pf fully parallel so packets arriving can be processed by multiple CPU's? Do these need to be coming in from multiple interfaces or can even packets from one interface be distributed among multiple CPU's?
