Special promisc receive mode

Hello

I need to tell kernel that e. g. eth0 is a point-to-point link and that every ethernet frame should be treated this way:
1) Replace destination MAC with MAC of the eth0 network card
2) Process as normally

I tried to set up promisc mode but it seems to not work - it looks like the frames are intercepted, however are not treated as destinated for my host (are not forwared etc.)
