33 To compile this driver into the kernel,
34 place the following lines in your
35 kernel configuration file:
36 .Bd -ragged -offset indent
37 .Cd "options COMPAT_LINUXKPI"
38 .Cd "options RATELIMIT"
39 .Cd "options KERN_TLS"
47 To load the driver as a module at run-time,
48 run the following command as root:
49 .Bd -literal -offset indent
53 To load the driver as a
54 module at boot time, place the following lines in
56 .Bd -literal -offset indent
62 driver provides support for PCI Express Ethernet adapters based on
63 ConnectX-4/5/6 [Dx, Ex and Lx variants].
64 The driver supports Jumbo Frames, Transmit and Receive checksum offload,
65 TCP segmentation offload (TSO), Large Receive Offload (LRO),
66 HW Large Receive Offload (HW LRO), VLAN tag insertion and extraction,
67 VLAN checksum offload, VLAN TSO, hardware rate limiting (TXRTLMT),
68 stateless VxLAN hardware offload for receive and transmit,
69 HW TLS offload for transmit, Receive Side Steering (RSS) and
73 The network interface name is
75 which corresponds to a PCI function,
79 is a number starting at zero.
80 There is at most one network interface per PCI function.
