| 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. | |

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. | |

22 | WARNING: Enabling connected mode will trigger some packet |
| 23 | drops for multicast and UD mode traffic from this interface, | |
| 839fcaba MT |
24 | unless you limit mtu for these destinations to 2044. |

| 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). | |

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. | |

| cab00891 | 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. |
