slbServerFarmBindId is used to identify one or more
real servers for which slbDfpRealWeight applies to the
real server's slbRealOperWeight. The identification
is done by finding rows in slbServerFarmTable for which
slbServerFarmBindId matches slbDfpRealBindId. For each
identified server farm, extract the slbServerFarmName
and use this value together with slbDfpRealIpAddress
and slbDfpRealPort to identify the row in
slbRealTable.
