Yes - in nfsen.conf in the %sources definitions. Add -s as I described in my
ealier mail. ( optarg => .... )
These args are directly passed to nfcapd.

Yes - nfcapd does automatically recognise the sampling rate. The -s option is
only meant for those router software
releases, which don't do that, although sampling is configured.
o You can preset the sampling rate for nfcapd by setting the -s option.
o If sampling is announced from the router - this values overwrite the given -s
o hard core: setting -s -<rate> ( add minus sign ) locks the sampling rate for
nfcapd, regardless what the device announces.
This should hopefully fit for every setup.
