[NET] fib_rules: Mark rules detached from the device
Rules which match against device names in their selector can remain while the device itself disappears, in fact the device doesn't have to present when the rule is added in the first place. The device name is resolved by trying when the rule is added and later by listening to NETDEV_REGISTER/UNREGISTER notifications. This patch adds the flag FIB_RULE_DEV_DETACHED which is set towards userspace when a rule contains a device match which is unresolved at the moment. This eases spotting the reason why certain rules seem not to function properly. Signed-off-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
