Hauke Mehrtens 2e17c71095 kernel: Backport patch to automatically bring up DSA master when opening user port
Without this patch we have to manually bring up the CPU interface in
failsafe mode.

This was backported from kernel 5.12.

Subject: [PATCH] net: dsa: Include bridge addresses in assisted CPU port

assisted CPU port learning is enabled.
