Linux/FreeBSD Channel Bonding Interoperability

[Julian Elischer]

from what I'm reading about teql you can do this with a couple of methods..

ipfw and the 'fwd' rule
netgraph and ng_one2many

there may be more..

teql doesn't seem to modify the packets in any way, just to make them go 
across several links
so both of those should work I think.

the ipfw fwd method would require ip addresses on both interfaces.
the netgraph  method may be able to do it without that requirement.
(linking to an ng_eiface node with a single address).
