iptables mac destination filtering

I suppose it is because you do NOT know the destination MAC address. The
dest MAC address is found out first when the packets get out of iptables and
go to the NIC. Besides - you cannot find out the MAC address of the host
that is reachable over i.e. 3 hops. Recall the OSI layer system and it
should be clear. 

I think I am not wrong here. If so, please correct me.

I would like to know why it's not possible to filter on mac destination
address with iptables.
