2 tristate "IP-over-InfiniBand"
3 depends on NETDEVICES && INET && (IPV6 || IPV6=n)
5 Support for the IP-over-InfiniBand protocol (IPoIB). This
6 transports IP packets over InfiniBand so you can use your IB
9 See Documentation/infiniband/ipoib.txt for more information
11 config INFINIBAND_IPOIB_CM
12 bool "IP-over-InfiniBand Connected Mode support"
13 depends on INFINIBAND_IPOIB && EXPERIMENTAL
16 This option enables experimental support for IPoIB connected mode.
17 After enabling this option, you need to switch to connected mode through
18 /sys/class/net/ibXXX/mode to actually create connections, and then increase
19 the interface MTU with e.g. ifconfig ib0 mtu 65520.
21 WARNING: Enabling connected mode will trigger some
22 packet drops for multicast and UD mode traffic from this interface,
23 unless you limit mtu for these destinations to 2044.
25 config INFINIBAND_IPOIB_DEBUG
26 bool "IP-over-InfiniBand debugging" if EMBEDDED
27 depends on INFINIBAND_IPOIB
30 This option causes debugging code to be compiled into the
31 IPoIB driver. The output can be turned on via the
32 debug_level and mcast_debug_level module parameters (which
33 can also be set after the driver is loaded through sysfs).
35 This option also creates an "ipoib_debugfs," which can be
36 mounted to expose debugging information about IB multicast
37 groups used by the IPoIB driver.
39 config INFINIBAND_IPOIB_DEBUG_DATA
40 bool "IP-over-InfiniBand data path debugging"
41 depends on INFINIBAND_IPOIB_DEBUG
43 This option compiles debugging code into the data path
44 of the IPoIB driver. The output can be turned on via the
45 data_debug_level module parameter; however, even with output
46 turned off, this debugging code will have some performance
