5 Support for the IP-over-InfiniBand protocol (IPoIB). This

11 config INFINIBAND_IPOIB_CM
12 bool "IP-over-InfiniBand Connected Mode support"
13 depends on INFINIBAND_IPOIB
16 This option enables support for IPoIB connected mode. After
17 enabling this option, you need to switch to connected mode
18 through /sys/class/net/ibXXX/mode to actually create
19 connections, and then increase the interface MTU with
20 e.g. ifconfig ib0 mtu 65520.
22 WARNING: Enabling connected mode will trigger some packet
23 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 EXPERT
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 a directory tree under ipoib/ in
37 debugfs, which contains files that expose debugging
38 information about IB multicast groups used by the IPoIB
41 config INFINIBAND_IPOIB_DEBUG_DATA
42 bool "IP-over-InfiniBand data path debugging"
43 depends on INFINIBAND_IPOIB_DEBUG
45 This option compiles debugging code into the data path
46 of the IPoIB driver. The output can be turned on via the
47 data_debug_level module parameter; however, even with output
48 turned off, this debugging code will have some performance
