[GENETLINK]: Move command capabilities to flags.
This patch moves command capabilities to command flags. Other than being cleaner, saves several bytes. We increment the nlctrl version so as to signal to user space that to not expect the attributes. We will try to be careful not to do this too often ;-> Signed-off-by: Jamal Hadi Salim <hadi@cyberus.ca> Signed-off-by: David S. Miller <davem@davemloft.net>
