General:

Model of operation: All utilities use direct MAD access to perform their
operations. Operations that require QP 0 mads only, may use direct routed
mads, and therefore may work even in unconfigured subnets. Almost all
utilities can operate without accessing the SM, unless GUID to lid translation
is required.

Dependencies: Most utilities depend on libibmad and libibumad.
	All utilities depend on the ib_umad kernel module.

Multiple port/Multiple CA support: when no IB device or port is specified
	(see the "local umad parameters" below), the libibumad library
	selects the port to use by the following criteria:
	1. the first port that is ACTIVE.
	2. if not found, the first port that is UP (physical link up).

	If a port and/or CA name is specified, the libibumad library
	attempts to fulfill the user request, and will fail if it is not
	possible.
	For example:
	ibaddr 			# use the 'best port'
	ibaddr -C mthca1	# pick the best port from mthca1 only.
	ibaddr -P 2		# use the second (active/up) port from the
				  first available IB device.
	ibaddr -C mthca0 -P 2	# use the specified port only.

Common options & flags:
	Most diagnostics take the following flags. The exact list of supported
	flags per utility can be found in the usage message and can be shown
	using util_name -h syntax.

	# Debugging flags
	-d	raise the IB debugging level. May be used
		several times (-ddd or -d -d -d).
	-e	show umad send receive errors (timeouts and others)
	-h	show the usage message
	-v	increase the application verbosity level.
		May be used several times (-vv or -v -v -v)
	-V	show the internal version info.

	# Addressing flags
	-D	use directed path address arguments. The path
		is a comma separated list of out ports.
		Examples:
		"0" 		# self port
		"0,1,2,1,4"	# out via port 1, then 2, ...
	-G	use GUID address arguments. In most cases, it is the Port GUID.
		Examples:
		"0x08f1040023"
	-s <smlid>	use 'smlid' as the target lid for SA queries.

	# Local umad parameters:
	-C <ca_name>	use the specified ca_name.
	-P <ca_port>	use the specified ca_port.
	-t <timeout_ms>	override the default timeout for the solicited mads.

CLI notation: all utilities use the POSIX style notation,
	meaning that all options (flags) must precede all arguments
	(parameters).


Utilities descriptions:

ibstatus is a script which displays basic information obtained from the local
IB driver. Output includes LID, SMLID, port state, link width active, and port
physical state.

Syntax:
ibstatus [-h] [devname[:port]]...

Examples:

for the specified switch LID and the optional lid (mlid) range.
The default range is all valid entries in the range 1...FDBTop.

Syntax:
ibroute [options] <switch_addr> [<startlid> [<endlid>]]]

Non standard flags:
	-a	show all lids in range, even invalid entries.
	-n	do not try to resolve destinations.
	-M 	show multicast forwarding tables. In this case the range
		parameters are specifying mlid range.

tracing can be performed between source and destination nodes.

Syntax:
ibtracert [options] <src-addr> <dest-addr>

Non standard flags:
	-n		simple format; don't show additional information.
	-m <mlid>	show the multicast trace of the specified mlid.
