#66371 — Bug#951409: Marvell A38x ClearFog mvneta eth device regression

Package: src:linux
Version: 5.4.19-1
Severity: important

Recent armmp kernels fail to enable all available ethernet devices using 
the mvneta driver. On a ClearFog Base, booting the 4.19 Buster kernels 
works as expected, with eth0/eth1/eth2 all being present and available 
for use.

However, in booting more recent kernels, only the single eth0 device is 
available for use. The mvneta module is loaded and used in all cases, 
but doesn't seem to even acknowledge the existence of the other two 
devices.

The device tree for the ClearFog maps ethernet devices as 
f1070000.ethernet, f1030000.ethernet, and f1034000.ethernet. According 
to dmesg boot output, the f1070000 device is the only one which is 
available on newer kernels.

I've tested with 4.19.67-2+deb10u2 and confirmed it working, and tested 
with linux-image-5.2.0-2-armmp version 5.2.7-1 from snapshots and 
confirmed that it is not working as of that 5.2 build.

Thanks,
Joel

#66390 — Bug#951409: Confirmed fix to build required platform comphy as module

[Multipart message — attachments visible in raw view] — view raw

Thanks, I created an identical patch before seeing your update, tested 
and confirmed that building as a module is loaded during boot. I tried 
to submit a merge request to the repo, but don't have access to push 
branches, so I've also attached the resulting patch here.
