[BRIDGE]: set features based on enslaved devices
Make features of the bridge pseudo-device be a subset of the underlying devices. Motivated by Xen and others who use bridging to do failover. Signed-off-by: Catalin BOIE <catab at umrella.ro> Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: David S. Miller <davem@davemloft.net>
