Function Documentation

struct bnx2i_hba* bnx2i_find_hba_for_cnic ( struct cnic_dev *  cnic)
read

bnx2i_find_hba_for_cnic - maps cnic device instance to bnx2i adapter instance : pointer to cnic device instance

Definition at line 150 of file bnx2i_init.c.

int bnx2i_get_stats ( void *  handle)

bnx2i_get_stats - Retrieve various statistic from iSCSI offload : bnx2i_hba

function callback exported via bnx2i - cnic driver interface to retrieve various iSCSI offload related statistics.

Definition at line 390 of file bnx2i_init.c.

void bnx2i_identify_device ( struct bnx2i_hba *  hba)

bnx2i_identify_device - identifies NetXtreme II device type : Adapter structure pointer

This function identifies the NX2 device type and sets appropriate queue mailbox register access method, 5709 requires driver to access MBOX regs using bin mode

Definition at line 87 of file bnx2i_init.c.

void bnx2i_start ( void *  handle)

bnx2i_start - cnic callback to initialize & start adapter instance : transparent handle pointing to adapter structure

This function maps adapter structure to pcidev structure and initiates firmware handshake to enable/initialize on chip iscsi components This bnx2i - cnic interface api callback is issued after following 2 conditions are met - a) underlying network interface is up (marked by event 'NETDEV_UP' from netdev b) bnx2i adapter instance is registered

Definition at line 178 of file bnx2i_init.c.

void bnx2i_stop ( void *  handle)

bnx2i_stop - cnic callback to shutdown adapter instance : transparent handle pointing to adapter structure

driver checks if adapter is already in shutdown mode, if not start the shutdown process

Definition at line 237 of file bnx2i_init.c.

void bnx2i_ulp_exit ( struct cnic_dev *  dev)

bnx2i_ulp_exit - shuts down adapter instance and frees all resources : cnic device handle

Definition at line 359 of file bnx2i_init.c.

void bnx2i_ulp_init ( struct cnic_dev *  dev)

bnx2i_ulp_init - initialize an adapter instance : cnic device handle

Called from cnic_register_driver() context to initialize all enumerated cnic devices. This routine allocate adapter structure and other device specific resources.

Definition at line 334 of file bnx2i_init.c.

DEFINE_PER_CPU ( struct bnx2i_percpu_s  ,
