Rock64 flaky ethernet?

I've got an old-ish (2018 .. v2) Rock64 that hasn't been used much. I have 
fetched and booted it into the 13-RELEASE image:

FreeBSD-13.0-RELEASE-arm64-aarch64-ROCK64.img.xz	452690956	2021-Apr-09 06:46

I have written this to an 8GB generic micro-SD card. For good measure, I have 
written a recent Armbian image to the same brand and age of micro-SD card, so 
I have comparison material. (I could also write everything to the 32GB eMMC 
chip that's in the Rock64, if needed, but I'm holding off on that until I have 
something that works).

After boot, dwc0 gets an address from DHCP, and I start pinging 10.0.0.2 in my 
home network. I get ~3% packet loss if I'm lucky, more often around 7%. If I'm 
pinging a machine in the network and also pinging my Rock64 from that machine, 
I hit around 22% packet loss on both sides.

Armbian works fine - poweroff, swap SD card, power on - in the same setup.

With this kind of packet loss I can't really do anything with the board in 
FreeBSD; `pkg bootstrap` for instance seems to sit there forever.

.. ok, digging in the archives gets me lots of threads from june/july 2020 
about dwc timing, I'll dig through those first before carrying on.

PS. Pine H6 never did catch on in FreeBSD-land, did it. Pity, I've got a 
couple that I'd be happy enough to use instead of the Rock64 if they worked.
