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