The QL45212 Adapter Linux drivers and supporting documentation are available
at
dell.support.com . Table 3-1 describes the QL45212 Adapter Linux drivers.
The Linux drivers can be installed using a source Red Hat packet 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

Description
qed The Linux core module manages all PCI device resources (registers, host
interface queues, and so on). The qed core module directly controls the
firmware, handles interrupts, and is the interface for the qede driver. 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 QL45212 Adapter. This driver directly controls
the hardware and is responsible for sending and receiving Ethernet pack-
ets 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 RDMA over converged Ethernet (RoCE) driver. This driver works in
the open fabric enterprise distributions (OFED) environment in conjunction
with the qed core module and the qede Ethernet driver. qedr requires that
the libqedr user library be installed on the server.
