net: dsa: Keep the vlan_filtering setting in dsa_switch if it's global
The current behavior is not as obvious as one would assume (which is that, if the driver set vlan_filtering_is_global = 1, then checking any dp->vlan_filtering would yield the same result). Only the ports which are actively enslaved into a bridge would have vlan_filtering set. This makes it tricky for drivers to check what the global state is. So fix this and make the struct dsa_switch hold this global setting. Signed-off-by: Vladimir Oltean <olteanv@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
