Configuring Linux FCoE Offload
The Marvell FastLinQ 41xxx Series Adapter FCoE software consists of a single
kernel module called qedf.ko (qedf). The qedf module is dependent on additional
parts of the Linux kernel for specific functionality:
 qed.ko
is the Linux eCore kernel module used for common Marvell
FastLinQ 41xxx hardware initialization routines.
 libfcoe.ko
is the Linux FCoE kernel library needed to conduct FCoE
forwarder (FCF) solicitation and FCoE initialization protocol (FIP) fabric login
(FLOGI).
 libfc.ko
is the Linux FC kernel library needed for several functions,
including:
 Name server login and registration
 rport session management
 scsi_transport_fc.ko
is the Linux FC SCSI transport library used for
remote port and SCSI target management.
NOTE
FCoE offload is supported on all 41xxx Series Adapters. Some FCoE
features may not be fully enabled in the current release. For details, refer to
Appendix D Feature Constraints.
