This will enable the user to control the specific interface for connection establishment in case the host has more than 1 interface under the same subnet. E.g: Host interfaces configured as: - ib0 1.1.1.1/16 - ib1 1.1.1.2/16 Target interfaces configured as: - ib0 1.1.1.3/16 (listener interface) - ib1 1.1.1.4/16 the following connect command will go through host iface ib0 (default): nvme connect -t rdma -n testsubsystem -a 1.1.1.3 -s 1023 but the following command will go through host iface ib1: nvme connect -t rdma -n testsubsystem -a 1.1.1.3 -s 1023 -w 1.1.1.2 Signed-off-by: Max Gurtovoy <maxg@mellanox.com> Reviewed-by: Parav Pandit <parav@mellanox.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Sagi Grimberg <sagi@grimberg.me> Signed-off-by: Jens Axboe <axboe@fb.com>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
