[-Rhcdl -C <ca_name> -P <ca_port> -v <lt,hoq,vlstall> -S <guid> -D
iblinkinfo.pl reports the link info for each port of each switch active
in the IB fabric.
-R Recalculate the ibnetdiscover information, ie do not use the
cached information. This option is slower but should be used if
the diag tools have not been used for some time or if there are
other reasons to believe the fabric has changed.
Output only the switch specified by <guid> (hex format)
Output only the switch specified by the direct route path.
-l Print all information for each link on one line. Default is to
print a header with the switch information and then a list for
each port (useful for grep´ing output).
-d Print only switches which have a port in the "Down" state.
Verify additional switch settings
-c Print port capabilities (enabled and supported values)
-C <ca_name> use the specified ca_name for the search.
-P <ca_port> use the specified ca_port for the search.
