|
|
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 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.

|
---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.

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.
