Table 3-1 describes the 41xxx Series Adapter Linux drivers.
Install the Linux drivers using either a source Red Hat
®
Package Manager (RPM)
package or a kmod RPM package. The RHEL RPM packages are as follows:
qlgc-fastlinq-<version>.<OS>.src.rpm
qlgc-fastlinq-kmp-default-<version>.<arch>.rpm
The SLES source and kmp RPM packages are as follows:
qlgc-fastlinq-<version>.<OS>.src.rpm
qlgc-fastlinq-kmp-default-<version>.<OS>.<arch>.rpm
The following kernel module (kmod) RPM installs Linux drivers on SLES hosts
running the Xen Hypervisor:
qlgc-fastlinq-kmp-xen-<version>.<OS>.<arch>.rpm
The following source RPM installs the RDMA library code on RHEL and SLES
hosts:
qlgc-libqedr-<version>.<OS>.<arch>.src.rpm

Description
qed The qed core driver module directly controls the firmware, handles interrupts, and pro-
vides the low-level API for the protocol specific driver set. The qed interfaces with the
qede, qedr, qedi, and qedf drivers. The Linux core module manages all PCI device
resources (registers, host interface queues, and so on). The qed core module requires
Linux kernel version 2.6.32 or later. Testing was concentrated on the x86_64 architecture.
qede Linux Ethernet driver for the 41xxx Series Adapter. This driver directly controls the hard-
ware and is responsible for sending and receiving Ethernet packets on behalf of the Linux
host networking stack. This driver also receives and processes device interrupts on
behalf of itself (for L2 networking). The qede driver requires Linux kernel version 2.6.32 or
later. Testing was concentrated on the x86_64 architecture.
qedr Linux RoCE driver that works in the OpenFabrics Enterprise Distribution (OFED™) envi-
ronment in conjunction with the qed core module and the qede Ethernet driver..RDMA
user space applications also require that the libqedr user library is installed on the server
qedi Linux iSCSI-Offload driver for the 41xxx Series Adapters. This driver works with the Open
iSCSI library.y
qedf Linux FCoE-Offload driver for the 41xxx Series Adapters. This driver works with Open
FCoE library.
