Subject: [dpdk-dev] [PATCH v2 07/10] net/mlx5: convert port id action to indexed
Date: Thu, 16 Apr 2020 10:42:05 +0800 [thread overview]
Message-ID: <1587004928-328077-8-git-send-email-suanmingm@mellanox.com> (raw)
In-Reply-To: <1587004928-328077-1-git-send-email-suanmingm@mellanox.com>
This commit converts port id action 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.
