Generally interface address changes are expected to be synchronous.

Yeah, this bothers me a bit as well, but the address change calls come
in under spin_lock_bh(), and I'm reluctant to make an AdminQ call
under the _bh that could block for a few seconds.

So it's not about memory allocation but rather the fact that the device
might take a while to complete?

Can you start the operation synchronously yet complete it async?
