That isn't possible because the host machine state is unknown after a
timeout. The problem is not confined to TF based controllers and even
on TF based controllers, it's far too dangerous to continue as nothing
happened. That can easily lead to complete system lock up on quite a
few controllers due to fragile TF emulation layer.
The drive is full SATA. SETXFER doesn't mean anything to it. Let's
just skip it.
Thanks.
