FF - Frame Filter for OpenBSD

The idea is - compare mac addresses and IP address (listed in a hash
table for quick lookups)
If there is no entry drop the frame... otherwise let the frame get
decapusluted further up the stack.... well thats the idea... shouldn;t
be
too tricky (in theory.... haven;t looked at any code yet though)

This would not be apart of PF - as from what I have read the PF guys
don't want MAC address filtering within PF... I suppose packet filtering
doesn't include frames as it is too low a level..... thats why its called packet
filter?

We all know mac addrs and IP addrs can be spoofed with no problems...
but some still want to lock IP addresses to MAC addrs

Example scenario.... one of my friends runs a dedicated hosting
company.... the users have full root access to each box..... the company wishes to
tie IP addrs to mac addrs so that each box on the network can not allocate
IP addresses to itself..... the only way i can see this working is by doing
MAC address filtering.....

comments, ideas, flames?
