freebsd-nq/share/man/man4/mlx4en.4
Hans Petter Selasky 97549c34ec Move the ConnectX-3 and ConnectX-2 driver from sys/ofed into sys/dev/mlx4
like other PCI network drivers. The sys/ofed directory is now mainly
reserved for generic infiniband code, with exception of the mthca driver.

- Add new manual page, mlx4en(4), describing how to configure and load
mlx4en.

- All relevant driver C-files are now prefixed mlx4, mlx4_en and
mlx4_ib respectivly to avoid object filename collisions when compiling
the kernel. This also fixes an issue with proper dependency file
generation for the C-files in question.

- Device mlxen is now device mlx4en and depends on device mlx4, see
mlx4en(4). Only the network device name remains unchanged.

- The mlx4 and mlx4en modules are now built by default on i386 and
amd64 targets. Only building the mlx4ib module depends on
WITH_OFED=YES .

To compile this driver into the kernel,
place the following lines in your
kernel configuration file:
.Bd -ragged -offset indent
.Cd "options COMPAT_LINUXKPI"
.Cd "device mlx4"
.Cd "device mlx4en"
.Ed
.Pp
To load the driver as a module at run-time,
run the following command as root:
.Bd -literal -offset indent
kldload mlx4en
.Ed
.Pp
To load the driver as a

.Sh DESCRIPTION
Mellanox ConnectX adapter cards with Virtual Protocol Interconnect
(VPI) provide the highest performing and most flexible interconnect
solution for Enterprise Data Centers, High-Performance Computing, and
Embedded environments.
Clustered data bases, parallelized applications, transactional
services and high-performance embedded I/O applications will achieve
significant performance improvements resulting in reduced completion
time and lower cost per operation.
.Sh HARDWARE
The
.Nm
driver supports the following network adapters:
