i try to create a bonding interface " bond1" which has two slave port "eth0" and "eth1"
after i configed the slave, i found i can't save and apply, because i have not set up ip address and ip mask of "bond1"
but I want to config "bond1" as a layer 2 port which will add to a bridge,
it does not attend to be a layer 3 port.
The official does not provide a direct upgrade from OpenWrt 23 to 24 if I want to upgrade across versions, I think I need to back up the configuration and reinstall.
