BUG interface bandwidth display

Hi,

I have 2 RB600 with eth2—eth2 connected and eth3—eth3 connected too. I’m doing bandwidth test with a bonding interface and 2 EoIP tunnels, like in http://wiki.mikrotik.com/wiki/Bonding_Examples but with 2 ethernet interfaces.

Ether2 show me bad info. Almost double of real. It’s a bug? I’m using 3.5 in 2xRB600
