Subject: [PATCH v2 4/9] app/testpmd: fix packet transmission in noisy VNF engine
Date: Mon, 20 Feb 2023 17:40:58 +0100	[thread overview]
Message-ID: <20230220164103.3041538-5-david.marchand@redhat.com> (raw)
In-Reply-To: <20230220164103.3041538-1-david.marchand@redhat.com>

nb_rx relates to the number of packets received from the driver.
nb_tx is the total number of packets transmitted by this forward engine.

Fix the retry stage, for dequeued packets, as it was incorrectly
passing nb_rx / nb_tx as bounds of the tmp_pkts[] array, and fix tx stats
accordingly.

Fixes: 3c156061b938 ("app/testpmd: add noisy neighbour forwarding mode")
Cc: stable@dpdk.org
