netmap, selective processing.

[Adrian Chadd]

Hi,

Yes. You can write some matching code to match on what you care about
and reinject the rest back to the netmap "host interface" that you can
create. There's a way to grab both say, em0 for netmap and the host
side of em0 so you can reinject packets back up to the host stack and
get them from the host stack to process.

Luigi would know the details. I just stumbled across it when pecking around. :)
