config MLX5_CORE
tristate "Mellanox 5th generation network adapters (ConnectX series) core driver"
depends on MAY_USE_DEVLINK
depends on PCI
imply PTP_1588_CLOCK
imply VXLAN
default n
---help---
Core driver for low level functionality of the ConnectX-4 and
Connect-IB cards by Mellanox Technologies.
config MLX5_ACCEL
bool
config MLX5_FPGA
bool "Mellanox Technologies Innova support"
depends on MLX5_CORE
select MLX5_ACCEL
---help---
Build support for the Innova family of network cards by Mellanox
Technologies. 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
depends on IPV6=y || IPV6=n || MLX5_CORE=m
select PAGE_POOL
default n
---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_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
default n
---help---
MLX5 IPoIB offloads & acceleration support.
config MLX5_EN_IPSEC
bool "IPSec XFRM cryptography-offload accelaration"
depends on MLX5_ACCEL
depends on MLX5_CORE_EN
depends on XFRM_OFFLOAD
depends on INET_ESP_OFFLOAD || INET6_ESP_OFFLOAD
default n
---help---
Build support for IPsec cryptography-offload accelaration in the NIC.
Note: Support for hardware with this capability needs to be selected
for this option to become available.
config MLX5_EN_TLS
bool "TLS cryptography-offload accelaration"
depends on MLX5_CORE_EN
depends on TLS_DEVICE
depends on TLS=y || MLX5_CORE=m
depends on MLX5_ACCEL
default n
---help---
Build support for TLS cryptography-offload accelaration in the NIC.
Note: Support for hardware with this capability needs to be selected
for this option to become available.
