+port attach with socket path
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Attach a port specified by pci address or virtual device args and add extra
+devargs to it, which is imported from external process::
+
+   testpmd> port attach (identifier) mlx5_socket=(path)
+
+where:
+
+* ``identifier``: pci address or virtual device args.
+* ``path``: socket path to import arguments agreed by the external process.
+
+The mlx5 PMD enables to import CTX and PD created outside the PMD.
+It gets as devargs the device's ``cmd_fd`` and ``pd_handle``,
+then using those arguments to import objects.
+See :ref:`mlx5 driver options <mlx5_common_driver_options>` for more information.
+
+When ``cmd_fd`` and ``pd_handle`` arguments are coming from another process,
+the FD must be dup'd before being passed.
+In this function, testpmd initializes IPC socket to get FD using SCM_RIGHTS.
+It gets the external process socket path, then import the ``cmd_fd`` and
+``pd_handle`` arguments and add them to devargs list.
+After updating this, it calls the regular ``port attach`` function
+with extended identifier.
+
+For example, to attach a port whose pci address is ``0000:0a:00.0`` and its
+socket path is ``/var/run/import_ipc_socket``.
+
+.. code-block:: console
