This object indicates the initial interval of intelligent-timer for receiving
OSPF LSAs. When hwOspfv2LsaArriveStartIntvl is specified, you need also specify
hwOspfv2LsaArriveMaxIntvl and hwOspfv2LsaArriveHoldIntvl, but you cannot
specify hwOspfv2LsaArriveIntvl. Note that -1 is not a configurable value.
Instead, by set the intelligent timer to default value, it will get back to
default configuration.
