Log for wine relay trace

When running traffic watcher on wine (with pcap supported), An err Msgbox pops
out shows "This program works only on Ethernet networks." and when use

WINEDEBUG=+relay,+wpcap,+tid wine xxx.exe it shows this, which I think is wrong

0009:trace:wpcap:wine_pcap_datalink (0x7d8c1b08)
0009:Ret  wpcap.pcap_datalink() retval=00000071 ret=004078a7

The retval here seems to make no sense\

The app can be get via sourceforge:

https://sourceforge.net/projects/trafficwatcher/files/

The bug above is tested with ver 2.0.1

The attachment is the result of cutting full log with
cat log | grep wpcap
