hi, 
   pcap gives the timestamp of a packet using the ioctle call with flag SIOCGSTAMP.
Is it the same timestamp reported by radiotap header (i.e the time calculated in the driver tasklet )  ?
Can I use them as the key to compare packet trace from pcap capture and trace capture having the tsf timestamp ?
