Status for the TFTP Get operation, the SNMP manager need to set the
eocBrTFTPGetAction value to activate(1); and submit to the bridge
to start the TFTP Get procedure. The status (eocBrTFTPGetStatus)
will go from inProgress(1) status back to the initial
normalOrComplete(0) status. TFTP Get will attempt to retrieve
a firmware/driver file from the TFTP server whose address
is given by eocBrTFTPServer. The filename is given by
eocBrTFTPFilename. Both eocBrTFTPServer and
eocBrTFTPFilename must be correct for the TFTP operation to proceed.
