   4 Subject: [PATCH] ARM: dts: BCM5301X: Explicitly disable unused switch CPU
   5  ports
   6 MIME-Version: 1.0
   7 Content-Type: text/plain; charset=UTF-8
   8 Content-Transfer-Encoding: 8bit
   9
  10 When redescribing ports I assumed that missing "label" (like "cpu")
  11 means switch port isn't used. That was incorrect and I realized my
  12 change made Linux always use the first (5) CPU port (there are 3 of
  13 them).
  14
  15 While above should technically be possible it often isn't correct:
  16 1. Non-default switch ports are often connected to Ethernet interfaces
  17    not fully covered by vendor setup (they may miss MACs)
  18 2. On some devices non-default ports require specifying fixed link
  19
  20 This fixes network connectivity for some devices. It was reported &
  21 tested for Netgear R8000. It also affects Linksys EA9200 with its
  22 downstream DTS.
  23
  24 Fixes: ba4aebce23b2 ("ARM: dts: BCM5301X: Describe switch ports in the main DTS")
