Subject: [PATCH] examples/ipsec-secgw: fix IPsec performance drop
Date: Tue, 6 Feb 2024 18:08:11 +0530 [thread overview]
Message-ID: <20240206123811.3452587-1-rbhansali@marvell.com> (raw)
Single packet free using rte_pktmbuf_free_bulk() is dropping the
performance. On cn10k, maximum of ~4% drop observed for IPsec
event mode single SA outbound case.
To fix this issue, single packet free will use rte_pktmbuf_free
API.
Fixes: bd7c063561b3 ("examples/ipsec-secgw: use bulk free")
