  1 config INFINIBAND_IPOIB

  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.

 11 config 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.

 26 config 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.
 40 
 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.
