  1. config INFINIBAND_IPOIB
  2. tristate "IP-over-InfiniBand"
  3. depends on INFINIBAND && NETDEVICES && INET && (IPV6 || IPV6=n)
  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.
  8. See Documentation/infiniband/ipoib.txt for more information
  9. config INFINIBAND_IPOIB_CM
  10. bool "IP-over-InfiniBand Connected Mode support"
  11. depends on INFINIBAND_IPOIB && EXPERIMENTAL
  12. default n
  13. ---help---
  14. This option enables experimental support for IPoIB connected mode.
  15. After enabling this option, you need to switch to connected mode through
  16. /sys/class/net/ibXXX/mode to actually create connections, and then increase
  17. the interface MTU with e.g. ifconfig ib0 mtu 65520.
  18. WARNING: Enabling connected mode will trigger some
  19. packet drops for multicast and UD mode traffic from this interface,
  20. unless you limit mtu for these destinations to 2044.
  21. config INFINIBAND_IPOIB_DEBUG
  22. bool "IP-over-InfiniBand debugging" if EMBEDDED
  23. depends on INFINIBAND_IPOIB
  24. default y
  25. ---help---
  26. This option causes debugging code to be compiled into the
  27. IPoIB driver. The output can be turned on via the
  28. debug_level and mcast_debug_level module parameters (which
  29. can also be set after the driver is loaded through sysfs).
  30. This option also creates an "ipoib_debugfs," which can be
  31. mounted to expose debugging information about IB multicast
  32. groups used by the IPoIB driver.
  33. config INFINIBAND_IPOIB_DEBUG_DATA
  34. bool "IP-over-InfiniBand data path debugging"
  35. depends on INFINIBAND_IPOIB_DEBUG
  36. ---help---
  37. This option compiles debugging code into the data path
  38. of the IPoIB driver. The output can be turned on via the
  39. data_debug_level module parameter; however, even with output
  40. turned off, this debugging code will have some performance
  41. impact.
