I have 1 onboard network port, and 2 on a 10gbit Broadcom card. Bonding was enabled on eth0. I disabled bonding "because I didn't think I needed it, and unraid lost network connectivity and said a cable was unplugged. So, reboot--no dice, set back to bonded -no dice, reboot - -no dice. deleted network.cfg and network-rules.cfg and all is back to normal. Except my connections are still bonded.
