copybreaks help you..

I'll noticed this too and turned flow control off too yes. Useless to have,
it makes network debugging very hard. Much better to see packet drops at
the systems thats not able to keep up with load. And especially now with
6.2.15 when RX-stats counters finally is fixed. Thanks for fixing this.
