Chapter 5. Device Drivers

Emulex lpfc driver

The default interrupt configuration for the Emulex LPFC FC/FCoE driver has changed from INT-X to MSI-X. This is reflected by the lpfc_use_msi module parameter (in /sys/class/scsi_host/host#/lpfc_use_msi) being set to 2 by default, instead of the previous 0. For more information on this change, refer to Red Hat Enterprise Linux 6.2 Technical Notes.
