Hello,
I have a bonding interface configured for 2 x 1Gbps interfaces for "active-backup" mode using the " luci-proto-bonding" package. For whatever reason it will, occasionally switch over to "balance-rr" and start freaking out my switches.
ip -d -j link show bond-lan | jq gives me:

In the 
above state, I have the primary unplugged which is why the non-primary is the active link.
Here is my /etc/config/network:

I've used the scripted method of /etc/rc.local ... modprobe .... ip link set etc, but wanted a more transferable / upgradable config.
Am I doing something wrong or is there some problem with the luci-proto-bonding package not properly setting the mode?
