[dpdk-dev] [PATCH 05/20] net/ena: skip packet with wrong req_id

From: Rafal Kozik <rk at semihalf.com>

When invalid req_id is received, the reset should be handled by the
application, as it is indicating invalid rings state, so further Rx
is not making any sense.

Fixes: c2034976673d ("net/ena: add Rx out of order completion")
