[PATCH net 0/2] ionic: fix completion descriptor access

The first patch adds the missing dma_rmb() between the completion
publish checks and the reads of the descriptor payloads, suggested by
the Sashiko review from [1] for the second patch.

The second locates the completion within its slot from cq->desc_size
rather than a fixed stride, which is necessary when IONIC_Q_F_2X_CQ_DESC
(double-sized completion descriptors) is used (e.g. for hardware
timestamps).
