int mpt2sas_transport_add_expander_phy	(	struct MPT2SAS_ADAPTER *	ioc,
		struct _sas_phy *	mpt2sas_phy,
		Mpi2ExpanderPage1_t	expander_pg1,
		struct device *	parent_dev
	)

mpt2sas_transport_add_expander_phy - report expander phy to transport : per adapter object : mpt2sas per phy object : expander page 1 : parent device class object

Returns 0 for success, non-zero for failure.

Definition at line 916 of file mpt2sas_transport.c.

int mpt2sas_transport_add_host_phy	(	struct MPT2SAS_ADAPTER *	ioc,
		struct _sas_phy *	mpt2sas_phy,
		Mpi2SasPhyPage0_t	phy_pg0,
		struct device *	parent_dev
	)

mpt2sas_transport_add_host_phy - report sas_host phy to transport : per adapter object : mpt2sas per phy object : sas phy page 0 : parent device class object

Returns 0 for success, non-zero for failure.

Definition at line 849 of file mpt2sas_transport.c.

u8 mpt2sas_transport_done	(	struct MPT2SAS_ADAPTER *	ioc,
		u16	smid,
		u8	msix_index,
		u32	reply
	)

mpt2sas_transport_done - internal transport layer callback handler. : per adapter object : system request message index : MSIX table index supplied by the OS : reply message frame(lower 32bit addr)

Callback handler when sending internal generated transport cmds. The callback index passed is ioc->transport_cb_idx

Return 1 meaning mf should be freed from _base_interrupt 0 means the mf is freed from this function.

struct _sas_port* mpt2sas_transport_port_add ( struct MPT2SAS_ADAPTER *  ioc, u16  handle, u64  sas_address  )

read

mpt2sas_transport_port_add - insert port to the list : per adapter object : handle of attached device : sas address of parent expander or sas host Context: This function will acquire ioc->sas_node_lock.

Adding new port object to the sas_node->sas_port_list.

Returns mpt2sas_port.

	)

mpt2sas_transport_port_remove - remove port from the list : per adapter object : sas address of attached device : sas address of parent expander or sas host Context: This function will acquire ioc->sas_node_lock.

Removing object and freeing associated memory from the ioc->sas_port_list.

Return nothing.
