Add module parameter multipath_on_hba to enable/disable multi-port path topology support. By default this feature is enabled on SAS3.5 HBA device and disabled on SAS3 &SAS2.5 HBA devices. When this feature is disabled then driver uses a default PhysicalPort(PortID) number i.e. 255 instead of the PhysicalPort number provided by HBA firmware.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
