OK, dirty hack:
Always set samplerate to Max.
This probably means nasd will use rate conversion for most flows.
The correct fix could be to register an auSetSampleRateCB for each
flow, which will adjust the flows data to the new rate and could
probably also increase the rate (rate should always be min(Maxrate,max(all flow
rates)) IMHO).
