Bob-

I don't know what you mean by:

        

"the
collision of packets between the domains"
The only place within Ethernet that packets "collide" is:

        

Within a
single, half-duplex collision domain (i.e. CSMA/CD mode)
EFM will be a full duplex system so there will not be any
collisions.

There is contention for positioning/ordering of packets in queues in
switches. How that is done outside the scope of 802.3 completely and is
generally considered to be a proprietary matter of implementation
