No error messages? I think recently bridge started allowing IPs on bridge only, not on member interfaces... (there is some sysctl for temporary workaround, not recommended in general - it will be gome some day)

It works on member interfaces for the moment with the default sysctl values. That will/may change for 16. So, that's not the problem here. And to be frank, I don't understand what it is, to put it mildly.

Move your IP to the bridge and just attach the physical interface to the bridge.
