             the corresponding ifIndex.
             The LLID field, as defined in the [802.3ah], is a 2-byte
             register (15-bit field and a broadcast bit) limiting the
             number of virtual links to 32768.  Typically the number
             of expected virtual links in a PON is like the number of
             ONUs, which is 32-64, plus an additional entry for
             broadcast LLID (with a value of 0xffff)."
