config MLX4_EN
tristate "Mellanox Technologies 1/10/40Gbit Ethernet support"
depends on PCI && NETDEVICES && ETHERNET && INET
depends on PTP_1588_CLOCK_OPTIONAL
select MLX4_CORE
help
This driver supports Mellanox Technologies ConnectX Ethernet
devices.
config MLX4_EN_DCB
bool "Data Center Bridging (DCB) Support"
default y
depends on MLX4_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 MLX4_CORE
tristate
depends on PCI
select NET_DEVLINK
default n
config MLX4_DEBUG
bool "Verbose debugging output" if (MLX4_CORE && EXPERT)
depends on MLX4_CORE
default y
help
This option causes debugging code to be compiled into the
mlx4_core driver. The output can be turned on via the
debug_level module parameter (which can also be set after
the driver is loaded through sysfs).
config MLX4_CORE_GEN2
bool "Support for old gen2 Mellanox PCI IDs" if (MLX4_CORE)
depends on MLX4_CORE
default y
help
Say Y here if you want to use old gen2 Mellanox devices in the
driver.
