Subject: [PATCH] tulip: Assign default MAC address if not specified mainline
 inclusion commit 052c2579b89b0d87debe8b05594b5180f0fde87d category: bugfix
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

---------------------------------------------------------------

The MAC of the tulip card is stored in the EEPROM and at startup
tulip_fill_eeprom() is called to initialize the EEPROM with the MAC
address given on the command line, e.g.:
    -device tulip,mac=00:11:22:33:44:55

In case the mac address was not given on the command line,
tulip_fill_eeprom() initializes the MAC in EEPROM with 00:00:00:00:00:00
which breaks e.g. a HP-UX guest.

Fix this problem by moving qemu_macaddr_default_if_unset() a few lines
up, so that a default mac address is assigned before tulip_fill_eeprom()
initializes the EEPROM.
