This is the last driver that we have had work with our Miatas. Packets are properly sent, but do not appear to be received. The bootp server acknowledges the request and sends its response, but the client eventually just times out, never seeing the answering packets. Again, I've confirmed that the bootp request and response are both on the wire with a sniffer. Here is the relevant portions of the boot log.
Server is on same subnet as client.
Unix domain sockets 0.16 for Linux NET3.038. 77 b0, IRQ 24. No NFS server available, giving up. Unable to mount root fs via NFS, trying floppy.
