I got a new USB ethernet adapter because the old one had lots of issues (hence the gist in the first place). But it still uses the same Realtek 8153 chip although am using the native driver though now, AppleUSBECM.kext
In terms of my previous issues, I remember that when I clicked the little lock in the browser to view the cert, it would crash my computer. But the disconnects that required a restart were the bigger issue. (personal reference link)
I'm currently running macOS Mojave 10.14
I second 43n79w. I bought a RTL8156B unbranded USB dongle for $20 to test some 2.5GbE devices. RTL8156 seems to work with cdc_ncm well on M1. I can pull around 215MiB/s on RTL8156B to two WiFi 6 clients. 215MiB/s is probably still bottlenecked by wireless clients, I will buy another RTL8156B dongle for cheap ($18-20) to test.
[Update Apr 9, 2022]
Bought a second RTL8156B off Amazon, from the cheapest generic brand I could find; cost $18 + tax.
Retested RTL8156B on Apple M1 MBP using cdc_ncm driver; iperf3 to Intel i9 Ubuntu 20.04.
Results: M1 send, i9 receive: 1.79 Gbps (iperf3; bmon 220.32MiB)
M1 receive, i9 send: 2.36 Gbps (iperf3; bmon 281.49MiB)
RTL8156B does not work so well on Intel i9 Ubuntu 20.04, kernel 5.13. I need to manually load the r8152 mod and hard bind the device to the driver to get the same 208MiB/s. This is a digression from the topic.
[Update Apr 9, 2022]
Connected two RTL8156B to i9 Ubuntu; assigned into two separate network namespaces; iperf3 double sessions between
Results: two adapters simultaneously send and receive 2.34 Gbps (bmon RX 290.02MiB, TX 281.43MiB)
I just contacted Realtek tech support to see whether they still write RTL8153 driver targeting aarch64 architecture. I asked them to provide source code for x86_64 architecture so other programmers can try to re-target the driver for aarch64 (is this even possible? I am ill-educated in embedded system and CS in general)
