Hi Jakub

Before that change, it used phylib. The same is true with phylib, you
need to tell phylib it should not advertise pause. How you do it is
different, but the basic issue is the same. Anybody doing a backport
past 4bb043262878is going to need a different fix, but the basic issue
is there all the way back to when the driver was added.
