thank you for info! 
i tried disable EEE via ethtool by add this in /etc/rc.local
ethtool --set-eee lan1 eee off
ethtool --set-eee lan2 eee off
ethtool --set-eee lan3 eee off
ethtool --set-eee wan eee off
And.. no effect. VMWare in bridge mode still loses connection (host machine does not lose connection). Enabling/disabling EEE does not help.
