[Qemu-devel] 2nd try: [PATCH] fix for bad macaddr of e1000 in Windows 2003 server with original Microsoft driver

[Naphtali Sprei <nsprei@redhat.com>]

After comments from quintela@trasno.org and mst@redhat.com, here's the 
2nd try:


The sequence of reading from eeprom is "offset by one" moved because of 
a false detection
of a clock cycle after an eeprom reset. Keeping the last clock value 
after a reset keeps it in sync.
