   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.

  14         default n
  15         ---help---
  16           This option enables experimental support for IPoIB connected mode.
  17           After enabling this option, you need to switch to connected mode through
  18           /sys/class/net/ibXXX/mode to actually create connections, and then increase
  19           the interface MTU with e.g. ifconfig ib0 mtu 65520.
  20
  21           WARNING: Enabling connected mode will trigger some
  22           packet drops for multicast and UD mode traffic from this interface,
  23           unless you limit mtu for these destinations to 2044.

  25 config INFINIBAND_IPOIB_DEBUG
  26         bool "IP-over-InfiniBand debugging" if EMBEDDED
  27         depends on INFINIBAND_IPOIB
  28         default y
  29         ---help---
  30           This option causes debugging code to be compiled into the
  31           IPoIB driver.  The output can be turned on via the
  32           debug_level and mcast_debug_level module parameters (which
  33           can also be set after the driver is loaded through sysfs).
  34
  35           This option also creates an "ipoib_debugfs," which can be
  36           mounted to expose debugging information about IB multicast
  37           groups used by the IPoIB driver.

  39 config INFINIBAND_IPOIB_DEBUG_DATA
  40         bool "IP-over-InfiniBand data path debugging"
  41         depends on INFINIBAND_IPOIB_DEBUG
  42         ---help---
  43           This option compiles debugging code into the data path
  44           of the IPoIB driver.  The output can be turned on via the
  45           data_debug_level module parameter; however, even with output
  46           turned off, this debugging code will have some performance
  47           impact.
