udev: link-config - move naming policy from udev rules This introduces a new key NamePolicy, which takes an ordered list of naming policies. The first successful one is applide. If all fail the value of Name (if any) is used. The possible policies are 'onboard', 'slot', 'path' and 'mac'. This patch introduces a default link file, which replaces the equivalent udev rule. 2013-10-28 00:19:59 +01:00			`[Link]`

udev: link-config - add mac address policy This introduces a new key MACAddressPolicy. The possible policies are 'persistent' and 'random'. 'persistent' will do nothing if the current address is the hardware address, but if the hardware does not have an address (or another address is set for whatever reason), we will generate an address which will be random, but persistent between boots (based on machineid and persistent netif name). 'random' will do nothing if the kernel already set a random address, otherwise it will generate a random one and use that instead. This patch sets MACAddressPolicy=persistent in the default .link file. 2013-10-28 00:19:59 +01:00			`MACAddressPolicy=persistent`
