Subject: [PATCH 15/20] net/cnxk: use raw mbuf free on inline sec err
Date: Mon, 7 Feb 2022 12:59:27 +0530	[thread overview]
Message-ID: <20220207072932.22409-15-ndabilpuram@marvell.com> (raw)
In-Reply-To: <20220207072932.22409-1-ndabilpuram@marvell.com>

Use raw mbuf free on inline sec error to simulate
HW NPA free instead of doing rte_pktmbuf_free(). This
is needed as the callback will not be called from
DPDK lcore.

Fixes: 69daa9e5022b ("net/cnxk: support inline security setup for cn10k")
Cc: stable@dpdk.org
