-Subject: [PATCH] net: dsa: felix: Fix CPU port assignment when not last port
-
-On the NXP LS1028A, there are 2 Ethernet links between the Felix switch
-and the ENETC:
-- eno2 <-> swp4, at 2.5G
-- eno3 <-> swp5, at 1G
-
-Only one of the above Ethernet port pairs can act as a DSA link for
-tagging.
-
-When adding initial support for the driver, it was tested only on the 1G
-eno3 <-> swp5 interface, due to the necessity of using PHYLIB initially
-(which treats fixed-link interfaces as emulated C22 PHYs, so it doesn't
-support fixed-link speeds higher than 1G).
-
-After making PHYLINK work, it appears that swp4 still can't act as CPU
-port. So it looks like ocelot_set_cpu_port was being called for swp4,
-but then it was called again for swp5, overwriting the CPU port assigned
-in the DT.
-
-It appears that when you call dsa_upstream_port for a port that is not
-defined in the device tree (such as swp5 when using swp4 as CPU port),
-its dp->cpu_dp pointer is not initialized by dsa_tree_setup_default_cpu,
-and this trips up the following condition in dsa_upstream_port:
-
-	if (!cpu_dp)
-		return port;
-
-So the moral of the story is: don't call dsa_upstream_port for a port
-that is not defined in the device tree, and therefore its dsa_port
-structure is not completely initialized (ds->num_ports is still 6).
-
