Innova network cards are comprised of a ConnectX chip and an FPGA chip on one board. If you select this option, the mlx5_core driver will include the Innova FPGA core and allow building sandbox-specific client drivers. config MLX5_CORE_EN bool "Mellanox 5th generation network adapters (ConnectX series) Ethernet support" depends on NETDEVICES && ETHERNET && INET && PCI && MLX5_CORE select PAGE_POOL select DIMLIB help Ethernet support in Mellanox Technologies ConnectX-4 NIC. config MLX5_EN_ARFS bool "Mellanox MLX5 ethernet accelerated receive flow steering (ARFS) support" depends on MLX5_CORE_EN && RFS_ACCEL default y help Mellanox MLX5 ethernet hardware-accelerated receive flow steering support, Enables ethernet netdevice arfs support and ntuple filtering. config MLX5_EN_RXNFC bool "Mellanox MLX5 ethernet rx nfc flow steering support" depends on MLX5_CORE_EN default y help Mellanox MLX5 ethernet rx nfc flow steering support Enables ethtool receive network flow classification, which allows user defined flow rules to direct traffic into arbitrary rx queue via ethtool set/get_rxnfc API. config MLX5_MPFS bool "Mellanox Technologies MLX5 MPFS support" depends on MLX5_CORE_EN default y help Mellanox Technologies Ethernet Multi-Physical Function Switch (MPFS) support in ConnectX NIC. MPFs is required for when multi-PF configuration is enabled to allow passing user configured unicast MAC addresses to the requesting PF. config MLX5_ESWITCH bool "Mellanox Technologies MLX5 SRIOV E-Switch support" depends on MLX5_CORE_EN && NET_SWITCHDEV default y help Mellanox Technologies Ethernet SRIOV E-Switch support in ConnectX NIC. E-Switch provides internal SRIOV packet steering and switching for the enabled VFs and PF in two available modes: Legacy SRIOV mode (L2 mac vlan steering based). Switchdev mode (eswitch offloads). config MLX5_BRIDGE bool depends on MLX5_ESWITCH && BRIDGE default y help mlx5 ConnectX offloads support for Ethernet Bridging (BRIDGE). Enable adding representors of mlx5 uplink and VF ports to Bridge and offloading rules for traffic between such ports.

Actions get attached to a Hardware offloaded classifiers and are invoked after a successful classification. Actions are used to overwrite the classification result, instantly drop or redirect and/or reformat packets in wire speeds without involving the host cpu. If set to N, TC offloads in both NIC and switchdev modes will be disabled.

If set to N, will not be able to configure tc rules with sample action. If unsure, set to Y config MLX5_CORE_EN_DCB bool "Data Center Bridging (DCB) Support" default y depends on MLX5_CORE_EN && DCB help Say Y here if you want to use Data Center Bridging (DCB) in the driver. If set to N, will not be able to configure QoS and ratelimit attributes. This flag is depended on the kernel's DCB support. If unsure, set to Y config MLX5_CORE_IPOIB bool "Mellanox 5th generation network adapters (connectX series) IPoIB offloads support" depends on MLX5_CORE_EN help MLX5 IPoIB offloads & acceleration support. config MLX5_EN_MACSEC bool "Connect-X support for MACSec offload" depends on MLX5_CORE_EN depends on MACSEC default n help Build support for MACsec cryptography-offload acceleration in the NIC. config MLX5_EN_IPSEC bool "Mellanox Technologies IPsec Connect-X support" depends on MLX5_CORE_EN depends on XFRM_OFFLOAD depends on INET_ESP_OFFLOAD || INET6_ESP_OFFLOAD help Build support for IPsec cryptography-offload acceleration in the NIC. config MLX5_EN_TLS bool "Mellanox Technologies TLS Connect-X support" depends on TLS_DEVICE depends on TLS=y || MLX5_CORE=m depends on MLX5_CORE_EN help Build support for TLS cryptography-offload acceleration in the NIC. config MLX5_SW_STEERING bool "Mellanox Technologies software-managed steering" depends on MLX5_CORE_EN && MLX5_ESWITCH select CRC32 default y help Build support for software-managed steering in the NIC. config MLX5_SF bool "Mellanox Technologies subfunction device support using auxiliary device" depends on MLX5_CORE && MLX5_CORE_EN help Build support for subfuction device in the NIC. A Mellanox subfunction device can support RDMA, netdevice and vdpa device. It is similar to a SRIOV VF but it doesn't require SRIOV support. config MLX5_SF_MANAGER bool depends on MLX5_SF && MLX5_ESWITCH default y help Build support for subfuction port in the NIC. A Mellanox subfunction port is managed through devlink. A subfunction supports RDMA, netdevice and vdpa device. It is similar to a SRIOV VF but it doesn't require SRIOV support.
