From: Viacheslav Ovsiienko
> The Rx queue completion consumer index got temporary wrong value pointing
> to the midst of the compressed CQE session. If application crashed at the
> moment the next queue restart caused handling wrong CQEs pointed by index
> and losing consuming index synchronization, that made reliable queue restart
> impossible.
