Re: [Qemu-discuss] Coldfire 5282 Support

OK so really even though I see the driver sending the ARP requests, they’re not 
actually ever making it to the host, even though the PCAP file shows them. In 
other words, the PCAP file is "on the guest side" of the connection not "the 
host side of the connection". Correct?

If that’s the case I’ll go back to being mystified and go look at the source as 
you suggest. Because that means that QEMU is not replying to the requests.

Right?

Thanks again guys.
