10503 | * This routine is to be called to attach a device with SLI-3 interface spec | |
10504 | * to the PCI subsystem. When an Emulex HBA with SLI-3 interface spec is | |
10505 | * presented on PCI bus, the kernel PCI subsystem looks at PCI device-specific | |
10506 | * information of the device and driver to see if the driver state that it can | |
10507 | * support this kind of device. If the match is successful, the driver core | |
10508 | * invokes this routine. If this routine determines it can claim the HBA, it | |
10509 | * does all the initialization that it needs to do to handle the HBA properly. | |
10510 | * | |
10511 | * Return code | |
10512 | * 0 - driver can claim the device | |
10513 | * negative value - driver can not claim the device | |
