Please can you send us your .dts file.
Thanks

Sorry it has taken so long to get around to this. I've done some
testing with 4.9.78:
VF610 based ZII devel B with 88E6352 and 88E6185 switches: Works fine
Kirkwood based DIR665 with 88E6171: Works fine.
Armada XP based WRT1900AC with a 88E6172 switch: Works fine
The 6161 is a member of the 6165 family. That family contains 6123,
6161, and 6165. I don't have any of them. So i cannot specifically
test this switch family.
I think to make progress, you are going to need to perform a git bisect
to work out what makes it work in later kernels.

Please could you try cherry-picking:
ec8378bb4d8e ("net: dsa: mv88e6xxx: 6161 uses global 2 for PHY access")
0ac64c394900 ("net: dsa: mv88e6xxx: mv88e6161 uses mv88e6320 stats snapshot")
5ebe31d7b20f ("net: dsa: mv88e6xxx: Have 6161/6123 use EDSA tags")
The first one probably fixes your PHY issue. The second will fix
ethtool -S. The last one is just nice to have, helps when using
tcpdump on the master interface.
Thanks go to Chris Healy for pointing out these patches.
