Subject: [dpdk-dev] [PATCH v3 2/2] security: add reserved bitfields
Date: Mon, 18 Oct 2021 10:52:47 +0530	[thread overview]
Message-ID: <20211018052247.1082570-2-gakhil@marvell.com> (raw)
In-Reply-To: <20211018052247.1082570-1-gakhil@marvell.com>

In struct rte_security_ipsec_sa_options, for every new option
added, there is an ABI breakage, to avoid, a reserved_opts
bitfield is added to for the remaining bits available in the
structure.
Now for every new sa option, these reserved_opts can be reduced
and new option can be added.

v3:
- added a comment for requesting user to clear reserved_opts.
- removed LIST_END enumerators patch. It will be handled separately.
