   4        ---help---
   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.

  11config INFINIBAND_IPOIB_CM
  12        bool "IP-over-InfiniBand Connected Mode support"
  13        depends on INFINIBAND_IPOIB
  14        default n
  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.

  26config INFINIBAND_IPOIB_DEBUG
  27        bool "IP-over-InfiniBand debugging" if EXPERT
  28        depends on INFINIBAND_IPOIB
  29        default y
  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.

  41config 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.
