Does this work when interfaces being bonded do not support link state
like VF's and some other virtual devices (like vmxnet3?).

I am concerned that the flag to say whether device support LSC or not
is in drv_flags which is normally invariant. So either bond has to simulate
link state if slave devices do not support (by polling) or provide another
mechanism for application to determine availablity of link state.
