This is a limitation in the FEC support in QEMU.
This works on real ColdFire hardware (which do support the
FEC MIB stats registers from offset 0x200 - so not 5272).
I sent this patch to the qemu dev list a couple of weeks
back which fixes qemu:
http://lists.gnu.org/archive/html/qemu-devel/2017-01/msg01781.html
I do not believe it has been picked up by QEMU mainline yet
(I will probably have to resend and push a little to get that done).
QEMU upstream can sometimes take a while before they are merging patches,
but usually it helps containing the maintainer of this part of the
source tree directly.
Unfortunately, mcf5208 is currently unmaintained [1]:
mcf5208
S: Orphan
F: hw/m68k/mcf5208.c
F: hw/m68k/mcf_intc.c
F: hw/char/mcf_uart.c
F: hw/net/mcf_fec.c
But you can try getting into touch with Laurent Vivier who is the
new maintainer of the m68k target. I have CC'ed him.

Use scripts/get_maintainer.pl on your patch to find the people.
This patch is on the network part, so you should cc:
Jason Wang <jasowang@xxxxxxxxxx> (odd fixer:Network devices)
If you cc me, you add more chances to have a review ;)
I tried the patch on top of 2.8.0 qemu release and it works for me
with Linux Kernel 4.9.
If you can send a "Tested-by:" to the mailing list, it would be great.
Thanks for the hint and patch!
I hope Greg's patch get included in the next qemu release.
Btw: Laurent, are you m68k with mmu support are going to be included
upstream? I always carry an old binary for any m68k with mmu testing.
I'm working to have the FPU included for now, that will allow to have
the linux-user qemu enabled for 680x0 upstream.
I have a 68040 MMU implementation that I will send after this step.
I didn't have a look to the ColdFire MMU (is there one?), but as 68040
is not the same as the 68030 one, I don't expect it works with coldfire.
