I got the following to work. Edit /boot/config/network.cfg. Change BONDNICS[0] order to be what you want. Note: Changing static ip or other network settings may make network.cfg regenerate and you will lose this setting. But, it does survive a reboot. BONDNICS[0]="eth0 eth1 eth2"
to
BONDNICS[0]="eth1 eth0 eth2"
