Re: swaping ring slots between NIC ring and Host ring does not always success

Re: swaping ring slots between NIC ring and Host ring does not always success

Hi, there must be some wrong with your setting because slot indexes must be sequential and in your case they are not (see the jump from 295 to 474 and then back from 485 to 296, and the numerous interleavings that you are seeing later). I have no idea of the cause but typically this pattern is wha
