This 6 transports IP packets over InfiniBand so you can use your IB 7 device as a fancy NIC. 8 9 See Documentation/infiniband/ipoib.txt for more information 10 11config INFINIBAND_IPOIB_CM 12 bool "IP-over-InfiniBand Connected Mode support" 13 depends on INFINIBAND_IPOIB && EXPERIMENTAL 14 default n 15 ---help--- 16 This option enables experimental support for IPoIB connected mode. 17 After enabling this option, you need to switch to connected mode through 18 /sys/class/net/ibXXX/mode to actually create connections, and then increase 19 the interface MTU with e.g. ifconfig ib0 mtu 65520. 20 21 WARNING: Enabling connected mode will trigger some 22 packet drops for multicast and UD mode traffic from this interface, 23 unless you limit mtu for these destinations to 2044. 24 25config INFINIBAND_IPOIB_DEBUG 26 bool "IP-over-InfiniBand debugging" if EMBEDDED 27 depends on INFINIBAND_IPOIB 28 default y 29 ---help--- 30 This option causes debugging code to be compiled into the 31 IPoIB driver. The output can be turned on via the 32 debug_level and mcast_debug_level module parameters (which 33 can also be set after the driver is loaded through sysfs). 34 35 This option also creates an "ipoib_debugfs," which can be 36 mounted to expose debugging information about IB multicast 37 groups used by the IPoIB driver. 38 39config INFINIBAND_IPOIB_DEBUG_DATA 40 bool "IP-over-InfiniBand data path debugging" 41 depends on INFINIBAND_IPOIB_DEBUG 42 ---help--- 43 This option compiles debugging code into the data path 44 of the IPoIB driver. The output can be turned on via the 45 data_debug_level module parameter; however, even with output 46 turned off, this debugging code will have some performance 47 impact. 48
