Hi,
Code like this is making me wounder about the split between MAC
driver, DSA driver and DSA tag driver. Or if it should actually be a
pure switchdev driver?
If there some open architecture documentation for this device?
What are these ports about?
+static int airoha_dev_open(struct net_device *dev)
+{
+ struct airoha_eth *eth = netdev_priv(dev);
+ int err;
+
+ if (netdev_uses_dsa(dev))
+ airoha_fe_set(eth, REG_GDM1_INGRESS_CFG, GDM1_STAG_EN_MASK);
+ else
+ airoha_fe_clear(eth, REG_GDM1_INGRESS_CFG, GDM1_STAG_EN_MASK);
Does that imply both instances of the GMAC are not connected to the
switch? Can one be used with a PHY?

page 107 (text for 9.1.1 is relevant but not a complete match). In the
EN7581 case there is a 5 port switch in the place of GMAC1 (one switch
port is connected to GDM1).
This is documentation for another SoC but it should hopefully answer
your questions.
