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.
