enum sci_port_states - port state machine states : port has successfully been stopped. In this state no new IO operations are permitted. This state is entered from the STOPPING state. : port is in the process of stopping. In this state no new IO operations are permitted, but existing IO operations are allowed to complete. This state is entered from the READY state. : port is now ready. Thus, the user is able to perform IO operations on this port. This state is entered from the STARTING state. : port is started and ready but has no active phys. : port is started and ready and there is at least one phy operational. : port is started and there was an add/remove phy event. This state is only used in Automatic Port Configuration Mode (APC) : port is in the process of performing a hard reset. Thus, the user is unable to perform IO operations on this port. This state is entered from the READY state. : port has failed a reset request. This state is entered when a port reset request times out. This state is entered from the RESETTING state.

sci_port_add_phy() - : This parameter specifies the port in which the phy will be added. : This parameter is the phy which is to be added to the port.
This method will add a PHY to the selected port. This method returns an enum sci_status. SCI_SUCCESS the phy has been added to the port. Any other status is a failure to add the phy to the port.
Definition at line 1196 of file port.c.
sci_port_get_properties() - This method simply returns the properties regarding the port, such as: physical index, protocols, sas address, etc. : this parameter specifies the port for which to retrieve the physical index. : This parameter specifies the properties structure into which to copy the requested information.
Indicate if the user specified a valid port. SCI_SUCCESS This value is returned if the specified port was valid. SCI_FAILURE_INVALID_PORT This value is returned if the specified port is not valid. When this value is returned, no data is copied to the properties output parameter.

This method is called by the PHY object when the link is detected. if the port wants the PHY to continue on to the link up state then the port layer must return true. If the port object returns false the phy object must halt its attempt to go link up. : The port associated with the phy object. : The phy object that is trying to go link up.
true if the phy object can continue to the link up condition. true Is returned if this phy can continue to the ready state. false Is returned if can not continue on to the ready state. This notification is in place for wide ports and direct attached phys. Since there are no wide ported SATA devices this could become an invalid port configuration.

sci_port_remove_phy() - : This parameter specifies the port in which the phy will be added. : This parameter is the phy which is to be added to the port.
This method will remove the PHY from the selected PORT. This method returns an enum sci_status. SCI_SUCCESS the phy has been removed from the port. Any other status is a failure to add the phy to the port.
