 *
 * -Description-
 *
 * The Ekinops interface naming scheme is overly verbose (see example).
 * The ifDescr and ifName returned by the device are the same. This
 * script reduces ifDescr to slot/card type/interface and sets ifAlias
 * to the user defined description found on the interface's configuration
 * on the Ekinops shelf.
 *
 * Example:
 * ifName: EKINOPS/C600HC/13/PM_10010-MR/S10-Client10(PORT_Number 10)
 * ifDescr: 13/PM_10010-MR/S10-Client10
 * ifAlias: PORT_Number 10
