Well, that appears to be one potential flaw in the protocol - there's
nothing guaranteeing ordered delivery in Ethernet.  You'll *probably*
get it on a non-switched Ethernet, assuming that the transmitting driver
(and card) transmit packets in FIFO order, but I could imagine a switch
not preserving FIFO order.

(There's also no guarantee of reliable delivery....)

Nobody's added such a call, so it'd have to be added.
