2 tristate "IP-over-InfiniBand"

6 Support for the IP-over-InfiniBand protocol (IPoIB). This
7 transports IP packets over InfiniBand so you can use your IB
10 See Documentation/infiniband/ipoib.txt for more information
12 config INFINIBAND_IPOIB_CM
13 bool "IP-over-InfiniBand Connected Mode support"
14 depends on INFINIBAND_IPOIB && EXPERIMENTAL
17 This option enables experimental support for IPoIB connected mode.
18 After enabling this option, you need to switch to connected mode through
19 /sys/class/net/ibXXX/mode to actually create connections, and then increase
20 the interface MTU with e.g. ifconfig ib0 mtu 65520.
22 WARNING: Enabling connected mode will trigger some
23 packet drops for multicast and UD mode traffic from this interface,
24 unless you limit mtu for these destinations to 2044.
26 config INFINIBAND_IPOIB_DEBUG
27 bool "IP-over-InfiniBand debugging" if EMBEDDED
28 depends on INFINIBAND_IPOIB
31 This option causes debugging code to be compiled into the
32 IPoIB driver. The output can be turned on via the
33 debug_level and mcast_debug_level module parameters (which
34 can also be set after the driver is loaded through sysfs).
36 This option also creates an "ipoib_debugfs," which can be
37 mounted to expose debugging information about IB multicast
38 groups used by the IPoIB driver.
40 config INFINIBAND_IPOIB_DEBUG_DATA
41 bool "IP-over-InfiniBand data path debugging"
42 depends on INFINIBAND_IPOIB_DEBUG
44 This option compiles debugging code into the data path
45 of the IPoIB driver. The output can be turned on via the
46 data_debug_level module parameter; however, even with output
47 turned off, this debugging code will have some performance
