Not only that, but increasing the buffer length beyond that of a few frames 
would allow us more leniency in the ISR.  One of the reasons the early TE 
series cards had this high interrupt requirement was due to there being next 
to no buffering; if we didn't get in there immediately and retrieve the data, 
it'd be overrun.  Bigger buffers make for higher latencies, this is true, but 
as another poster mentioned; if you're already hitting an ethernet 
connection, you're not overly concerned about this.
