Description of problem:
If I change default MAC address on onboard Ethernet controller in ifcfg-eth0,
network on this interface not work


Version-Release number of selected component (if applicable):
nForce linux drivers 1.0-0233, 1.0-0236 and 1.0-0241 with kernel 2.4.18-3,
2.4.18-5, 2.4.18-10

How reproducible:
Always

Steps to Reproduce:
STEP 1.
ifcfg-eth script without MAC-address setting look like this:
---[begin /etc/sysconfig/network-scripts/ifcfg-eth0]---
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=static
IPADDR=192.168.1.4
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
# MACADDR=00:10:DC:1D:D1:40
---[end /etc/sysconfig/network-scripts/ifcfg-eth0]---

Network work fine:
---cut---

[root@localhost bug-report]# ifconfig

[root@localhost bug-report]# ping 192.168.1.1

---cut---


STEP 2.
I uncomment MACADDR="00:50:04:71:8D:89" in
/etc/sysconfig/network-scripts/ifcfg-eth0 script:
------[begin /etc/sysconfig/network-scripts/ifcfg-eth0]---
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=static
IPADDR=192.168.1.4
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
MACADDR=00:10:DC:1D:D1:40
---[end /etc/sysconfig/network-scripts/ifcfg-eth0]

STEP 3.
And reboot.
After that network is unreacheble:
---cut---
