> The XDomain protocol messages may start as soon as Thunderbolt control
> channel is started. This means that if the other host starts sending
> ThunderboltIP packets early enough they will be passed to the network
> driver which then gets confused because its resume hook is not called
> yet.
> 
> Fix this by unregistering the ThunderboltIP protocol handler when
> suspending and registering it back on resume.
