+Subject: [PATCH] ARM: dts: BCM5301X: Explicitly disable unused switch CPU
+ ports
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+When redescribing ports I assumed that missing "label" (like "cpu")
+means switch port isn't used. That was incorrect and I realized my
+change made Linux always use the first (5) CPU port (there are 3 of
+them).
+
+While above should technically be possible it often isn't correct:
+1. Non-default switch ports are often connected to Ethernet interfaces
+   not fully covered by vendor setup (they may miss MACs)
+2. On some devices non-default ports require specifying fixed link
+
+This fixes network connectivity for some devices. It was reported &
+tested for Netgear R8000. It also affects Linksys EA9200 with its
+downstream DTS.
+
+Fixes: ba4aebce23b2 ("ARM: dts: BCM5301X: Describe switch ports in the main DTS")

+Subject: [PATCH] ARM: dts: BCM5301X: Set fixed-link for extra Netgear R8000
+ CPU ports
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Ports 5 and 7 are disabled by default because the standard use case is
+for port 8 to manage all CPU directed traffic. For experimentation
+purposes however it is desirable to provide adequate properties such
+that people can experiment with using different ports without having to
+figure out their configuration. Some of the use cases include but are
+not limited to doubling or tripling the bandwidth by leveraging the
+additional ports/Ethernet MAC combinations.
