Subject: [dpdk-dev] [PATCH v2 01/10] net/mlx5: reorganize fate actions as union
Date: Thu, 16 Apr 2020 16:34:22 +0800 [thread overview]
Message-ID: <1587026071-422636-2-git-send-email-suanmingm@mellanox.com> (raw)
In-Reply-To: <1587026071-422636-1-git-send-email-suanmingm@mellanox.com>
Currently, one flow only has one fate action, the fate actions members
in the flow struct can be reorganized as union to save the memory for
flow struct.
This commit reorganizes the fate actions as union, the act_flags helps
to identify the fate action type when flow destroys.
