------> I have a virtual interface that Round Robins packets
over the actual physical interface. ( modified ng_etherchannelbonding). But, 
the receiver is
getting the packets out-of-order - as expected, when packets
are of different size, but, I am
not understanding, why,even when the 2 NICs are identical and
packets are of MTU size, reordering is occuring.

Any clues welcome.

I was  trying to see if the reason is the fact that each NIC puts up a lot 
of packets at a time to the TX DMA Area - and so, is it possible
in any way to gain a better contol over the actual sending of packets.
