 	  This driver supports the on-chip 1/10Gbit Ethernet controller on
 	  PA Semi's PWRficient line of chips.
 
-config MLX4_EN
-	tristate "Mellanox Technologies 10Gbit Ethernet support"
-	depends on PCI && INET
-	select MLX4_CORE
-	select INET_LRO
-	help
-	  This driver supports Mellanox Technologies ConnectX Ethernet
-	  devices.
-
-config MLX4_CORE
-	tristate
-	depends on PCI
-	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).
