>
> The Rx completion queue doorbell field needs to be updated after the last
> CQE decompressed. For the weaker memory model processors, the compiler
> barrier is not sufficient to guarantee the order of these operations, so use
> the coherent I/O memory barrier to make sure these fields are updated in
> order.
