config INFINIBAND_IPOIB
	tristate "IP-over-InfiniBand"
	depends on NETDEVICES && INET && (IPV6 || IPV6=n)
	---help---
	  Support for the IP-over-InfiniBand protocol (IPoIB). This
	  transports IP packets over InfiniBand so you can use your IB
	  device as a fancy NIC.

	  See Documentation/infiniband/ipoib.txt for more information

config INFINIBAND_IPOIB_CM
	bool "IP-over-InfiniBand Connected Mode support"
	depends on INFINIBAND_IPOIB && EXPERIMENTAL
	default n
	---help---
	  This option enables experimental support for IPoIB connected mode.
	  After enabling this option, you need to switch to connected mode through
	  /sys/class/net/ibXXX/mode to actually create connections, and then increase
	  the interface MTU with e.g. ifconfig ib0 mtu 65520.

	  WARNING: Enabling connected mode will trigger some
	  packet drops for multicast and UD mode traffic from this interface,
	  unless you limit mtu for these destinations to 2044.

config INFINIBAND_IPOIB_DEBUG
	bool "IP-over-InfiniBand debugging" if EMBEDDED
	depends on INFINIBAND_IPOIB
	default y
	---help---
	  This option causes debugging code to be compiled into the
	  IPoIB driver.  The output can be turned on via the
	  debug_level and mcast_debug_level module parameters (which
	  can also be set after the driver is loaded through sysfs).

	  This option also creates an "ipoib_debugfs," which can be
	  mounted to expose debugging information about IB multicast
	  groups used by the IPoIB driver.

config INFINIBAND_IPOIB_DEBUG_DATA
	bool "IP-over-InfiniBand data path debugging"
	depends on INFINIBAND_IPOIB_DEBUG
	---help---
	  This option compiles debugging code into the data path
	  of the IPoIB driver.  The output can be turned on via the
	  data_debug_level module parameter; however, even with output
	  turned off, this debugging code will have some performance
	  impact.
