ditto.  I'd like to import a couple of features on a per-feature base 
rather than doing a complete import which isn't possible anymore due to 
SMP and routing code changes.

Submit your list of features and I'll see what I can do this weekend.  My 
list includes:

- keep state and flags S/SA to default
- improved state table purgeing (this is internal, but a huge benefit)
- interface handling (groups etc.)
- pfsync / pflog update (not 100% sure about these due to libpcap / 
tcpdump dependency)

While at it, I might also introduce needed ABI breakage for netgraph 

Anything else?
