patch to disable "Bind to MAC address" for slave devices
Here's a simple patch for system-config-network-1.3.99.12 to disable the "Bind to MAC address" option on bond slave devices.

Description of problem: If eth0 and eth1 are bonded as bond0, and you edit eth1 with system-config-network and bind it to its MAC address, it breaks the bond pair because it uses the MAC address from eth0. For example, given a system with eth0 00:11:22:33:44:55 eth1 00:11:22:33:44:FF Use s-c-network to edit eth1, go to the Hardware Device tab, enable "Bind to MAC address", and hit the Probe button, and it will put the bond0 (same as eth0) MAC address in /etc/sysconfig/network-scripts/ifcfg-eth1 as HWADDR=00:11:22:33:44:55 Either the Probe function needs to correctly probe for the MAC address, or s-c-network should not allow one to edit slave interfaces. Version-Release number of selected component (if applicable): system-config-network-1.3.99.12-1.el5 How reproducible: every time Steps to Reproduce: 1. configure a system so eth0 and eth1 are bonded 2. launch system-config-network 3. select eth1 and hit Edit 4. go to Hardware Devices tab 5. enable "Bind to MAC address" and hit Probe button 6. click OK, File->Save, File->Quit 7. service network restart Actual results: bond0 fails to start correctly and this error is printed while starting network services: Device eth1 has different MAC address than expected, ignoring. eth1 is also renamed to an internal random name like dev10003 $ ifconfig -a ... dev10003 Link encap:Ethernet HWaddr 00:11:22:33:44:FF BROADCAST MULTICAST MTU:1500 Metric:1 ... Expected results: s-c-network prevents the user from corrupting the bond configuration Additional info:
