6	  Support for the IP-over-InfiniBand protocol (IPoIB). This
7	  transports IP packets over InfiniBand so you can use your IB
8	  device as a fancy NIC.

13	bool "IP-over-InfiniBand Connected Mode support"
14	depends on INFINIBAND_IPOIB
15	default n
16	---help---
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.
22
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.

30	default y
31	---help---
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).
36
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
40	  driver.

42config INFINIBAND_IPOIB_DEBUG_DATA
43	bool "IP-over-InfiniBand data path debugging"
44	depends on INFINIBAND_IPOIB_DEBUG
45	---help---
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
50	  impact.
