I don't know the answer, but I would like to know how did you determine that
eth0 (is it /dev/eth0?) is the wireless, etc.
What I have used comes with WinPCAP, with WpdPack there are several examples, in
Examples-pcap/iflist the resulting program lists your network interfaces, as this:
\Device\NPF_{9E387891-E631-4411-B604-0DE577B8EA67}
Description: Intel(R) PRO/1000 MT Desktop Adapter (Microsoft's Packet
Scheduler)
Loopback: no
Address Family: #2
Address Family Name: AF_INET
Address: 192.168.10.2
Netmask: 255.255.255.0
Broadcast Address: 255.255.255.255
As you can see, there is no MAC address, or info about the address being set by
DHCP, but that probably could be obtained. My question above is because I would
prefer to use /dev/eth1 that "\Device\NPF_...".
