bonding mode 4 monitoring:

we can not just check if MII Status is up for bonding mode 4, since the kernel will always report the bond device as UP
even if all cables are disconneccted.

For mode 4, ignore the status of the bond device and instead chek if at least one slave interface is up
when determining if the device is good or bad
