An NDIS driver sorts packets between stacks by offering them to the 
stacks in turn. When a stack takes the packet, that's it. The packet
is gone. Running two TCP/IP stacks over an NDIS driver will always 
create some problems, as some packets, intended for both stacks, will
only reach one. Still more lossage will be caused by one stack 
erroneously accepting packets intended for the other. With two stacks
of the same type and the same IP address, identifying packets is a 
problem. The usual result of this is that the stack loaded last gets 
all the packets.
