bridge: update sysfs link names if port device names have changed
Links for each port are created in sysfs using the device name, but this could be changed after being added to the bridge. As well as being unable to remove interfaces after this occurs (because userspace tools don't recognise the new name, and the kernel won't recognise the old name), adding another interface with the old name to the bridge will cause an error trying to create the sysfs link. This fixes the problem by listening for NETDEV_CHANGENAME notifications and renaming the link. https://bugzilla.kernel.org/show_bug.cgi?id=12743 Signed-off-by: Simon Arlott <simon@fire.lp0.eu> Acked-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S.
