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

  15         ---help---
  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.
  21
  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

  30         ---help---
  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).
  35
  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
  39           driver.

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