| 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. | |

17 | This option enables support for IPoIB connected mode. After |
| 18 | enabling this option, you need to switch to connected mode | |
| 19 | through /sys/class/net/ibXXX/mode to actually create | |
| 20 | connections, and then increase the interface MTU with | |
| 21 | e.g. ifconfig ib0 mtu 65520. | |

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

| 32 | This option causes debugging code to be compiled into the | |
| 33 | IPoIB driver. The output can be turned on via the | |
| 34 | debug_level and mcast_debug_level module parameters (which | |
| 35 | can also be set after the driver is loaded through sysfs). | |
| 36 | ||
| 37 | This option also creates an "ipoib_debugfs," which can be | |
| 38 | mounted to expose debugging information about IB multicast | |
| 39 | groups used by the IPoIB driver. | |

| cab00891 | 45 | This option compiles debugging code into the data path |
| 1da177e4 LT |
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. |
