But we're using GMII to the switch....and that workaround
code wasn't in active in my old kernel (it was there, but
commented out).

Any other thoughts?    Has anyone seen this symptom before?

Okay....I found it!    Started poking at the UCCE registers
and found that the FIFO sizes weren't right.   This led me
to find a bug in my ucc_geth interface to the fixed-link
PHY driver:  the code to reconfigure the MURAM FIFO's for
Gigabit operation wasn't being executed for no-phy configs!
All is well once I changed this.

Sorry for the noise.....   (glad I found this before
submitting my patch!   ;-)

yeah ucc_geth should be made aware of fixed-links on startup; UCCs
aren't like TSECs that know what MII type they're on.

setting phy-connection-type to certain strings containing a
'g' in the device tree should do the trick, too..:)
