Subject: [PATCH] ARM: dts: BCM5301X: Explicitly disable unused switch CPU
|
|
ports

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.
|
|
|
|
