[Winpcap-users] About the packet drops and use of pcap_stats_ex()

I have made these experiments :
PC captures data packets from a FPGA board.
1, I made a Loop back test that can verify there is no packet drops
between FPGA TO FPGA.
2Each data packets from FPGA board has a sequence number. Then PC can
figure that there are packets drops. (the packets number that pc gets
does not match the sequence of the packets).
3, call the pcap_stats_ex() , the result is : ps_drop=0 . That means
there is no packets drops between the kernel buffer to user buffer.
According to above , Packet drops could occur in the system netcard to
winPcap kernel driver. Is this conclusion right ?
Is it is right , what is the suggestion ? Can it be improved to use a
more professional net card ?
