- config INFINIBAND_IPOIB
- tristate "IP-over-InfiniBand"
- depends on NETDEVICES && INET && (IPV6 || IPV6=n)
- select INET_LRO
- ---help---
- Support for the IP-over-InfiniBand protocol (IPoIB). This
- transports IP packets over InfiniBand so you can use your IB
- device as a fancy NIC.
- See Documentation/infiniband/ipoib.txt for more information
- config INFINIBAND_IPOIB_CM
- bool "IP-over-InfiniBand Connected Mode support"
- depends on INFINIBAND_IPOIB && EXPERIMENTAL
- default n
- ---help---
- This option enables experimental support for IPoIB connected mode.
- After enabling this option, you need to switch to connected mode through
- /sys/class/net/ibXXX/mode to actually create connections, and then increase
- the interface MTU with e.g. ifconfig ib0 mtu 65520.
- WARNING: Enabling connected mode will trigger some
- packet drops for multicast and UD mode traffic from this interface,
- unless you limit mtu for these destinations to 2044.
- config INFINIBAND_IPOIB_DEBUG
- bool "IP-over-InfiniBand debugging" if EMBEDDED
- depends on INFINIBAND_IPOIB
- default y
- ---help---
- This option causes debugging code to be compiled into the
- IPoIB driver. The output can be turned on via the
- debug_level and mcast_debug_level module parameters (which
- can also be set after the driver is loaded through sysfs).
- This option also creates an "ipoib_debugfs," which can be
- mounted to expose debugging information about IB multicast
- groups used by the IPoIB driver.
- config INFINIBAND_IPOIB_DEBUG_DATA
- bool "IP-over-InfiniBand data path debugging"
- depends on INFINIBAND_IPOIB_DEBUG
- ---help---
- This option compiles debugging code into the data path
- of the IPoIB driver. The output can be turned on via the
- data_debug_level module parameter; however, even with output
- turned off, this debugging code will have some performance
- impact.
