So, I have tested today, and the results are great.

I hit my server hard with transferring a 72GB file to an SMB mount on the local
network, and then I copied that file over from the SMB mount to backblaze B2
with rclone (--transfers 32). The system did 250Mbps at its peak. Here's a
munin chart about it: https://i.imgur.com/yg6R6ii.png

No watchdog timeouts whatsoever, no link drops, and the system stayed snappy
the entire time, while I was observing the copying.

I think we can safely say now that the new Realtek driver is stable and I'd
really like to have it merged into the GENERIC kernel.

My only concern about the driver is these lines in the dmesg:
---
This product is covered by one or more of the following patents:
US6,570,884, US6,115,776, and US6,327,625.
---

I hope this doesn't mean that the FreeBSD project can't use the driver in its
kernel tree.
