net: dsa: convert cross-chip notifiers to iterate using dp
The majority of cross-chip switch notifiers need to filter in some way over the type of ports: some install VLANs etc on all cascade ports. The difference is that the matching function, which filters by port type, is separate from the function where the iteration happens. So this patch needs to refactor the matching functions' prototypes as well, to take the dp as argument. In a future patch/series, I might convert dsa_towards_port to return a struct dsa_port *dp too, but at the moment it is a bit entangled with dsa_routing_port which is also used by mv88e6xxx and they both return an int port. So keep dsa_towards_port the way it is and convert it into a dp using dsa_to_port. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
