Update hba_port's sas_address & phy_mask fields whenever a direct expander or sas/sata target devices are added or removed. When any direct attached device is discovered then driver: - Gets the hba_port object corresponding to device's PhysicalPort number; - Updates the hba_port's sas_address field with device's SAS Address; - Updates the hba_port's phy_mask filed with device's narrow/wide port Phy number bits; - If a sas/sata end device (not only direct-attached devices) is added then corresponding sas_device object's port variable is assigned with hba_port object's address whose port_id matches the device's PhysicalPort number. - If an expander device is added then corresponding sas_expander object's port variable is assigned with hba_port object's address whose port_id matches the expander device's PhysicalPort number. When any direct attached device is detached then driver will delete the hba_port object corresponding to device's PhysicalPort number. Whenever any HBA phy's link (of direct attached device's port) comes up then update the phy_mask field of corresponding hba_port object.

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.
