As the PPP main device (either a simple or old style vlan device) is freed when 
PPP interfaces are reloaded; interface device specific config (eg 
mtu/macaddr/...) is lost as the interface config is not re-applied on the newly 
created device.
Patch fixes the issue by re-applying the interface device config after the main 
device is claimed and is having default config.
