Subject: [PATCH rfc 2/3] nvmet: Add fabrics ops to port
In-Reply-To: <20180322190303.10951-1-sagi@grimberg.me>
References: <20180322190303.10951-1-sagi@grimberg.me>
Message-ID: <20180322190303.10951-3-sagi@grimberg.me>

From: Israel Rukshin <israelr@mellanox.com>

Instead of getting the nvmet_fabrics_ops from nvmet_transports array
each time we want to use it, just take it directly from the port.
