2 # Mellanox driver configuration
6 tristate "Mellanox 5th generation network adapters (ConnectX series) 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 5th generation network adapters (ConnectX series) Ethernet support"
31 depends on NETDEVICES && ETHERNET && INET && PCI && MLX5_CORE
32 depends on IPV6=y || IPV6=n || MLX5_CORE=m
36 Ethernet support in Mellanox Technologies ConnectX-4 NIC.
39 bool "Mellanox MLX5 ethernet accelerated receive flow steering (ARFS) support"
40 depends on MLX5_CORE_EN && RFS_ACCEL
43 Mellanox MLX5 ethernet hardware-accelerated receive flow steering support,
44 Enables ethernet netdevice arfs support and ntuple filtering.
47 bool "Mellanox MLX5 ethernet rx nfc flow steering support"
48 depends on MLX5_CORE_EN
51 Mellanox MLX5 ethernet rx nfc flow steering support
52 Enables ethtool receive network flow classification, which allows user defined
53 flow rules to direct traffic into arbitrary rx queue via ethtool set/get_rxnfc
57 bool "Mellanox Technologies MLX5 MPFS support"
58 depends on MLX5_CORE_EN
61 Mellanox Technologies Ethernet Multi-Physical Function Switch (MPFS)
62 support in ConnectX NIC. MPFs is required for when multi-PF configuration
63 is enabled to allow passing user configured unicast MAC addresses to the
67 bool "Mellanox Technologies MLX5 SRIOV E-Switch support"
68 depends on MLX5_CORE_EN && NET_SWITCHDEV
71 Mellanox Technologies Ethernet SRIOV E-Switch support in ConnectX NIC.
72 E-Switch provides internal SRIOV packet steering and switching for the
73 enabled VFs and PF in two available modes:
74 Legacy SRIOV mode (L2 mac vlan steering based).
75 Switchdev mode (eswitch offloads).
77 config MLX5_CORE_EN_DCB
78 bool "Data Center Bridging (DCB) Support"
80 depends on MLX5_CORE_EN && DCB
82 Say Y here if you want to use Data Center Bridging (DCB) in the
84 If set to N, will not be able to configure QoS and ratelimit attributes.
85 This flag is depended on the kernel's DCB support.
89 config MLX5_CORE_IPOIB
90 bool "Mellanox 5th generation network adapters (connectX series) IPoIB offloads support"
91 depends on MLX5_CORE_EN
94 MLX5 IPoIB offloads & acceleration support.
97 bool "IPSec XFRM cryptography-offload accelaration"
99 depends on MLX5_CORE_EN
100 depends on XFRM_OFFLOAD
101 depends on INET_ESP_OFFLOAD || INET6_ESP_OFFLOAD
104 Build support for IPsec cryptography-offload accelaration in the NIC.
105 Note: Support for hardware with this capability needs to be selected
106 for this option to become available.
109 bool "TLS cryptography-offload accelaration"
110 depends on MLX5_CORE_EN
111 depends on TLS_DEVICE
112 depends on TLS=y || MLX5_CORE=m
113 depends on MLX5_ACCEL
116 Build support for TLS cryptography-offload accelaration in the NIC.
117 Note: Support for hardware with this capability needs to be selected
118 for this option to become available.
