Entries in the hpnicfSysBtmLoadTable are created and deleted using
the hpnicfSysBtmRowStatus object.
When a new row is being created and the number of entries is
hpnicfSysBtmLoadMaxNumber, the row with minimal value of
hpnicfSysBtmLoadTime and the value of hpnicfSysBtmFileType is none(2),
should be destroyed automatically.
