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