Linux driver for the 8400/3400 Series 10Gb network adapt-
ers. This driver directly controls the hardware and is respon-
sible for sending and receiving Ethernet packets on behalf of
the Linux host networking stack. This driver also receives
and processes device interrupts, both on behalf of itself (for
L2 networking) and on behalf of the bnx2fc (FCoE) and cnic
drivers.
The cnic driver provides the interface between QLogic's
upper layer protocol (storage) drivers and QLogic's
8400/3400 Series 10Gb network adapters. The CNIC mod-
ule works with the bnx2 and bnx2x network drives in the
downstream and the bnx2fc (FCoE) and bnx2i (iSCSI) driv-
ers in the upstream.
Linux iSCSI HBA driver to enable iSCSI offload on the
8400/3400 Series 10Gb network adapters.
Linux FCoE kernel mode driver used to provide a translation
layer between the Linux SCSI stack and the QLogic FCoE
firmware/hardware. In addition, the driver interfaces with the
networking layer to transmit and receive encapsulated FCoE
frames on behalf of open-fcoe's libfc/libfcoe for FIP/device
discovery.
