Subject: net/ena: skip packet with wrong request id
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=f00930d929151fc09914e6d61b827f9f81645324;p=dpdk.git

net/ena: skip packet with wrong request id

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")
