Subject: [dpdk-dev] [PATCH 05/10] net/mlx5: convert push VLAN resource to indexed
Date: Mon, 13 Apr 2020 09:11:44 +0800 [thread overview]
Message-ID: <1586740309-449310-6-git-send-email-suanmingm@mellanox.com> (raw)
In-Reply-To: <1586740309-449310-1-git-send-email-suanmingm@mellanox.com>
This commit converts the push VLAN resource to indexed.
Using the uint32_t index instead of pointer saves 4 bytes memory for the
flow handle. For millions flows, it will save several MBytes of memory.
