Another approach I've tried is to extract the DTB and convert it to a DTS from the Synology DSM installation PAT file. However, it has not worked, see below.
Download DSM from:
https://archive.synology.com/download/Os/DSM/6.2.4-25556
Extract file:
Install extract-dtb tool:
Extract dtb from uboot image.
I couldn't find anything online to solve or explain the EOF error.
Q. Does synology even use a DTS or do they rely on their synobios binary firmware to set up the hardware? (cluching at strews here)

Download DSM from:

Extract file:

Install extract-dtb tool:

I don't think this DSM Linux kernel has FDT support, it's too old. Any mention of DTB is probably just for Synology testing.
I'm reading the mvpp2 driver and searching it's history in kernel GiHub. There were instances where the problem looks quite similar.
I'll post some testing ideas tomorrow.

Thanks Bodhi.
I started looking for the specification documents for both the Marvell Amada 375 (88F6720) and the ETH Marvell 88E1514. Which may help with the DTS.
I cannot find anything for the Marvell Amada 375 (88F6720) (maybe under NDA???...), even the kernel docs only mentions the product brief and not the hardware specs.

More luck for the Marvell 88E1514

I could not find the Amada 375 datasheet either.
Please try these 2 tests. In each test we turn off auto negotiation.
1. With armada-375-synology-ds215j-jan-20.tar. Boot, log into Debian and
2. With armada-375-synology-ds215j_eth1.tar
Instead of ifdown/ifup, you could also remove/insert the ethernet cable.

ZooMoo,
Can you check your switch if all the ports are 1Gbs? is there 2.5 Gbs port on this switch?
Also, in Debian get some info in both test cases:

Eventhough we still have problem, this is pretty good.
Except for this
So perhaps we should iron that out before going further.

The datasheet seems to indicate that this box LAN chip 88E1514 is SGMII (not RGMII).
So this should be used: armada-375-synology-ds215j_sgmii.tar

I've tried to find the detailed specifications for the WD MyCloud Gen 2, but not much luck.
The only official support page for the WD Cloud Gen 2 is the slightly differently named "WD Cloud Mirror Gen 2"
WD Cloud Mirror (Gen 2)
https://support-en.wd.com/app/products/product-detailweb/p/137
Yet, there are no hardware specifications. I found the manual else where (https://www.manualslib.com/manual/1021099/Western-Digital-My-Cloud-Mirror.html), but there wasn't any room in the 140 pages for CPU/RAM/Ethernet hardware specifications.
The best info I've found is from Small Net Builder where they pulled apart the unit, took photos of the PCB and listed the hardware components. However, they found an Armada 385, not 375 CPU. So I'm not sure if this is correct.

It's a differrent box using Armada 385.
I think the Armada 375 datasheet is good to have (when and if I build u-boot for it), but not too relevant here. The 88E151x datasheet is quite relevant

The datasheet seems to indicate that this box LAN chip 88E1514 is SGMII (not RGMII).

ZooMoo,
I've looked at your boot log again. It turns out you actually have the 88E1510, not 88E1514.
Either that, or the kernel misidentified the chip.

Either that, or the kernel misidentified the chip.
Looking at the driver source, it looks like the 88E1510 is used as a catch all for the family of 88E151x PHY chips.
It also contains a workaround for the 88E1514 bug.

That's how this driver was written. Sometime you'll see a mix of other chip's functions into one. It reused common functions when it can. I guess the current driver just print the mask (151x) and ignore the last digit. IIRC, in the past I've seen the specific chip ID before in some kernel log.

Compared with the WDMyCloud Gen2:

I'm wondering if DS215j Ethernet is on MAC1, which is a PoE port. Did Synology advertise it with PoE as a feature?

So it's definitely is rgmii-id, MAC0. Same as the MyCloud Gen 2!
GPL:
It's a puzzle why the driver detected port = FIBRE. Should be Twist Pair (TP).
Perhaps this u-boot messed it up?

A puzzle indeed.
Given Synologies DSM uses the 3.x Kernel, then it may be a regression in later kernels (?).
I'd like to try compiling a 3.x kernel to see if it works and rule out a regression in the 6.x kernel.
How do you prepare the Debian-6.6.2-mvebu-tld-1-rootfs-bodhi.tar.bz2 file (https://forum.doozan.com/read.php?2,32146)?
Do you have a build script?

Synologies DSM 6.2 uses the v3.2.4 kernel which I compared to the stock kernel for the same version.
To get the respective kernel sources for the armada 375:
linux-3.x.txz
https://global.synologydownload.com/download/ToolChain/Synology%20NAS%20GPL%20Source/6.2-25556/armada375/linux-3.x.txz
Location of .config which shows the kernel version (# Linux/arm 3.2.40 Kernel Configuration):
./6.2-25556/linux-3.x/synoconfigs/armada375
NOTE: Compilation relies on synobios which is not provided, but is released for the DSM 7.1
(https://global.synologydownload.com/download/ToolChain/Synology%20NAS%20GPL%20Source/7.1.1-42962/armada375/synobios.txz)
Stock GNU/Linux kernel:
The DSM kernel-3.x has the following additional folders that the stock 3.2.40 kernel lacks.
I've not tried compiling the stock kernel yet. I'm not sure how to do it with the debootstrap approach.
Is the reason why the (newer) stock kernel (Debian-6.6.2-mvebu-tld-1-rootfs-bodhi.tar.bz2) even with the DTS does not work properly with the DS215j is it lacks these plat-armada/mech-armada375 files?

No. Those are in the old Linux architecture back in the days. Modern Linux kernels have a different architecture for SoCs that have been mainlined.
Marvell SoCs (MVEBU), including Armada 375 SoC, belongs to
Specifically, the network driver used in this DS215j
So while it's good to look at the old code, you should only look at patches that are specific to this DS215j. Synology patches are quite decent in that they have comments for patches, and follow good sw practice of using naming convention.
