[IPV4]: Add default config support after inetdev_init
Previously once inetdev_init has been called on a device any changes made to ipv4_devconf_dflt would have no effect on that device's configuration. This creates a problem since we have moved the point where inetdev_init is called from when an address is added to where the device is registered. This patch is the first half of a set that tries to mimic the old behaviour while still calling inetdev_init. It propagates any changes to ipv4_devconf_dflt to those devices that have not had the corresponding attribute set. The next patch will forcibly set all values at the point where inetdev_init was previously called. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.
