Detailed Description

struct isci_port - isci direct attached sas port object : several states constitute 'ready'. When exiting ready we need to take extra port-teardown actions that are skipped when exiting to another 'ready' state. : software port index : hardware port index : identifies phy members : phy mask for the port that are already part of the port : : reserver for port task scheduler workaround : reference count for outstanding commands : set during state transitions and notified : timeout start/stop operations
