New Revision: 322810
URL: https://svnweb.freebsd.org/changeset/base/322810
Log:
Add new mlx5ib(4) driver to the kernel source tree which supports
Remote DMA over Converged Ethernet, RoCE, for the ConnectX-4 series of
PCI express network cards.
There is currently no user-space support and this driver only supports
kernel side non-routable RoCE V1. The krping kernel module can be used
to test this driver. Full user-space support including RoCE V2 will be
added as part of the ongoing upgrade to ibcore from Linux 4.9. Otherwise
this driver is feature equivalent to mlx4ib(4). The mlx5ib(4) kernel
module will only be built when WITH_OFED=YES is specified.
MFC after: 2 weeks

+.Nm mlx5ib
+.Nd "Mellanox ConnectX-4 and ConnectX-4 LX based 100Gb, 50Gb, 40Gb, 25Gb and
10Gb network adapter driver"
+.Sh SYNOPSIS
+To compile this driver into the kernel,
+place these lines in your kernel configuration file:
+.Bd -ragged -offset indent
+.Cd "options COMPAT_LINUXKPI"
+.Cd "device mlx5"
+.Cd "device mlx5ib"
+.Ed
+.Pp
+To load the driver as a module at run-time,
+run this command as root:
+.Bd -literal -offset indent
+kldload mlx5ib
+.Ed
+.Pp
+To load the driver as a
+module at boot time, place this line in
+.Xr loader.conf 5 :
+.Bd -literal -offset indent

+.Ed
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for infiniband and Remote DMA over Converged Ethernet,
+RoCE, for PCI Express network adapters based on ConnectX-4 and ConnectX-4 LX.
+.br
+For further hardware information and questions related to hardware
+requirements, see
+.Pa http://www.mellanox.com/ .
+.Pp
+For more information on configuring this device, see
+.Xr ifconfig 8 .
+.Sh HARDWARE
+The
+.Nm
+driver supports 100Gb, 50Gb, 40Gb, 25Gb and 10Gb network adapters.
+ConnectX-4 supports: 10/20/25/40/50/56/100Gb/s speeds.
+ConnectX-4 LX supports: 10/25/40/50Gb/s speeds (and reduced power consumption):
