Vendor data is supposedly sent out under the Vendor-Specific attribute.
Even though the Netblazer says that it doesn't support them, AcctSessionTime,
AcctInputOctets, and AcctOutputOctets do get logged. What I don't see in
RadiusNT is any allowance for the Vendor-Specific attribute. Do I just
create a field called VendorSpecific to get this to log?
