2 # Mellanox driver configuration
6 tristate "Mellanox Technologies ConnectX-4 and Connect-IB core driver"
7 depends on MAY_USE_DEVLINK
12 Core driver for low level functionality of the ConnectX-4 and
13 Connect-IB cards by Mellanox Technologies.
19 bool "Mellanox Technologies Innova support"
23 Build support for the Innova family of network cards by Mellanox
24 Technologies. Innova network cards are comprised of a ConnectX chip
25 and an FPGA chip on one board. If you select this option, the
26 mlx5_core driver will include the Innova FPGA core and allow building
27 sandbox-specific client drivers.
30 bool "Mellanox Technologies ConnectX-4 Ethernet support"
31 depends on NETDEVICES && ETHERNET && INET && PCI && MLX5_CORE
32 depends on IPV6=y || IPV6=n || MLX5_CORE=m
35 Ethernet support in Mellanox Technologies ConnectX-4 NIC.
38 bool "Mellanox Technologies MLX5 MPFS support"
39 depends on MLX5_CORE_EN
42 Mellanox Technologies Ethernet Multi-Physical Function Switch (MPFS)
43 support in ConnectX NIC. MPFs is required for when multi-PF configuration
44 is enabled to allow passing user configured unicast MAC addresses to the
48 bool "Mellanox Technologies MLX5 SRIOV E-Switch support"
49 depends on MLX5_CORE_EN
52 Mellanox Technologies Ethernet SRIOV E-Switch support in ConnectX NIC.
53 E-Switch provides internal SRIOV packet steering and switching for the
54 enabled VFs and PF in two available modes:
55 Legacy SRIOV mode (L2 mac vlan steering based).
56 Switchdev mode (eswitch offloads).
58 config MLX5_CORE_EN_DCB
59 bool "Data Center Bridging (DCB) Support"
61 depends on MLX5_CORE_EN && DCB
63 Say Y here if you want to use Data Center Bridging (DCB) in the
65 If set to N, will not be able to configure QoS and ratelimit attributes.
66 This flag is depended on the kernel's DCB support.
70 config MLX5_CORE_IPOIB
71 bool "Mellanox Technologies ConnectX-4 IPoIB offloads support"
72 depends on MLX5_CORE_EN
75 MLX5 IPoIB offloads & acceleration support.
78 bool "IPSec XFRM cryptography-offload accelaration"
80 depends on MLX5_CORE_EN
81 depends on XFRM_OFFLOAD
82 depends on INET_ESP_OFFLOAD || INET6_ESP_OFFLOAD
85 Build support for IPsec cryptography-offload accelaration in the NIC.
86 Note: Support for hardware with this capability needs to be selected
87 for this option to become available.
