[Stable] DS620slim + Ugreen RTL8156BG

[maao666]

Summary

DS620slim + USB-A to C adapter + Ugreen RTL8156BG work very well.

I purchased the Ugreen NIC here:
Ugreen 2.5GbE Adapter

Update

I've been using it for over 3 weeks and no issue so far.

Details

Thermal

Thermal is excellent. This picture is under full load (both uplink and downlink).

Speed

Update: Now I'm able to achieve 2.49Gb bi-directional simultaneously.
These two screenshots are outdated.

The two screenshots are taken at the same time.
Ubuntu(10GbE) <===> Switch <===> Ugreen NIC (2.5GbE) - DS620slim

And here's a screenshot from DSM. No other interfaces enabled.

Stress Test

I've been tested for 4 hours continuously under full load and no problem detected so far.
Personally I think this is a better option than a 5GbE NIC given similar speed yet better stability.

Background

Previously I used the QNAP 5GbE Adapter with the AQC111 driver and DS620slim but this NIC randomly drops connection without any clue (would disconnect from a few hours up to 1.5 months).
That is very unlikely because of overheating and the surface of the NIC is not hot at all.
Also, the speed I can get with DS620slim is about 2.8Gbps at maximum so not a huge difference from a 2.5 GbE one (measured by iPerf3).

My DSM version: DSM 7.2.1-69057 Update 5

Thank you, @bb-qq !
