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.

---help---
|
|
This option enables 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.

---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 a directory tree under ipoib/ in
|
|
debugfs, which contains files that expose debugging
|
|
information about IB multicast groups used by the IPoIB
|
|
driver.

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.
