[PATCH 0/1] nvme-tcp: Add option to set the physical interface to be used when connecting over TCP sockets.

[Martin Belanger]

From: Martin Belanger <martin.belanger at dell.com>

In our application, we need a way to force TCP connections to go out a
specific IP interface instead of letting Linux select the interface
based on the routing tables. This patch adds the option 'host-triface'
to allow specifying the interface to use. Note that corresponding
changes to the nvme-cli utility will follow.

Martin Belanger (1):
  Add 'Transport Interface' (triface) option. This can be used to
    specify the IP interface to use for the connection. The driver uses
    that to set SO_BINDTODEVICE on the socket before connecting.
