Subject: [PATCH v2 3/8] nvme-fabrics: Expose nvmf_check_required_opts() globally
Date: Mon, 21 Jun 2021 08:10:41 +0300	[thread overview]
Message-ID: <20210621051046.28783-4-smalin@marvell.com> (raw)
In-Reply-To: <20210621051046.28783-1-smalin@marvell.com>

From: Prabhakar Kushwaha <pkushwaha@marvell.com>

nvmf_check_required_opts() is used to check if user provided opts has
the required_opts or not. if not, it will log which options are not
provided.

It can be leveraged by nvme-tcp-offload to check if provided opts are
supported by this specific vendor driver or not.

So expose nvmf_check_required_opts() globally.
