   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.

  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.

  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.

  42 config 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.
