When a fight gets stop so early my first thought was "oh shit, another controversy". But Davis was obviously hurt bad and it was a great stoppage. I have never seen someone wrestle with the ref for that long and still be so out of it after they had no idea how the fight ended. I think she was hurt by the punch when she was standing as in the replay you can see her reaction to it. Then the knee and Judo throw added to the damage. And the multiple blows after sealed it. That was like some weird sort of Judo/side-control crucifix. Maybe someone who knows more about the actual technique can explain what that was. But hard to put together a more versatile, damaging 16 seconds then that.
