Hi Hubert
Do the registers for the ports exist?

I'm wondering if we should add something like
.invalid_port_mask = BIT(2) | BIT(3) | BIT(4)
and
/* Setup Switch Port Registers */
for (i = 0; i < mv88e6xxx_num_ports(chip); i++) {
+ if (chip->info->invalid_port_mask & BIT(i) &&
+ !dsa_is_unused_port(ds, i))
+ return -EINVAL;
if (dsa_is_unused_port(ds, i)) {
err = mv88e6xxx_port_set_state(chip, i,
BR_STATE_DISABLED);
