 I've just took the last image for rock64 and rockpro64 to test on my
boards (I usually netboot but testing the image give a common reference
between everyone).
 As a reference the image I've burned on the sd are :
FreeBSD-13.0-CURRENT-arm64-aarch64-ROCK64-20200618-r362292.img.xz
FreeBSD-13.0-CURRENT-arm64-aarch64-ROCKPRO64-20200618-r362292.img.xz

 On Rock64 v2.0 (2017-0713) I see no issues, I got an IP from my dhcp
server and could install packages properly.
 Using iperf3 I have ~275Mbits/sec which isn't great but we're aware of
the bad perf of the dwc(4) driver.

 On RockPro64 v2.1 I also see no issues, iperf3 give the same speed
result for tx but rx is worse (~100Mbits/sec).

Søren, what are your hack for R40 (which do not have support for in
term of clock so I'm not surprise that you need "something" for it). 

 Charles, could you test the same image as me and see if that makes a
difference (but I doubt since not much changed recently that could
affect that).

 Cheers,
