Because of the bridge problem mentioned in the list, I had to setup 
bridge redirect target for packets to arrive at the real interfaces ( vs 
br0 ). However, when doing so, if the real interface has no IP address, 
it will cause kernel ooops due to accessing null pointers.

I made a small change here to avoid the kernel ooops :-

Not sure it will be relevent to your next release. If not, kindly ignore.
