+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
+       default n
+       ---help---
+         This option enables 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 EXPERT
+       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 a directory tree under ipoib/ in
+         debugfs, which contains files that 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.
