 switch, and add port@5

Hi,

finally get some time to bootup with this series on my r2.

I see that inserting the port@5 as cpu-port maps this as default-cpu because dsa-core uses first found cpu-port as
default (dsa_tree_setup_cpu_ports in dsa.c) and because of lower bandwidth (rgmii instead of trgmii) not the best choice.

But it look worse...network is currently broken (set both gmacs up).
I see arp-packets reaching remote side, but reponse is not received by r2

I have tested it on 6.2-rc8 (wan-port), maybe additional patches are needed?...userspace setup should be right.

so i added series on top of net-next (no additional patches except some basic like build-script,defconfig and such)...same result...

i'm not sure if i change the mapping from userspace back to eth0, so disabled port@5 in switch, now port6 is
cpu-port again and it works...so something is wrong with port5 of switch or gmac1.

regards Frank
