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
17 This option enables support for IPoIB connected mode. After
18 enabling this option, you need to switch to connected mode
19 through /sys/class/net/ibXXX/mode to actually create
20 connections, and then increase the interface MTU with
21 e.g. ifconfig ib0 mtu 65520.
23 WARNING: Enabling connected mode will trigger some packet
24 drops for multicast and UD mode traffic from this interface,
25 unless you limit mtu for these destinations to 2044.
27 config INFINIBAND_IPOIB_DEBUG
28 bool "IP-over-InfiniBand debugging" if EMBEDDED
29 depends on INFINIBAND_IPOIB
32 This option causes debugging code to be compiled into the
33 IPoIB driver. The output can be turned on via the
34 debug_level and mcast_debug_level module parameters (which
35 can also be set after the driver is loaded through sysfs).
37 This option also creates a directory tree under ipoib/ in
38 debugfs, which contains files that expose debugging
39 information about IB multicast groups used by the IPoIB
42 config INFINIBAND_IPOIB_DEBUG_DATA
43 bool "IP-over-InfiniBand data path debugging"
44 depends on INFINIBAND_IPOIB_DEBUG
46 This option compiles debugging code into the data path
47 of the IPoIB driver. The output can be turned on via the
48 data_debug_level module parameter; however, even with output
49 turned off, this debugging code will have some performance
