The number of passes remaining in the current
download attempt. Some agents (currently JetDirect
agents) require multiple passes through the download
file in order to download a firmware image. This
object indicates the number of passes remaining,
including the current pass. The object is
initialized by the agent to the number of passes
required to complete the download when the
corresponding instance of hpicfDownloadStatus is set
to 'active'. It is decremented by one each time a
pass completes.
