Rock64 dwc interface issues

[Charles]

Hi gonzo,


In 100Mbit mode the interface does not respond to any arp who-is 
requests (tcpdump). So no icmp request are send nor received the rock64.
Then I tried to connect the laptop directly to the rock64 (Interface to 
interface connection 1GBit) --> Same packet lost issue as before.

The tcpdump on dwc0 interface reports:

IP truncated-ip - 16384 bytes missing


I also tried to replace the /boot/dtb/rockchip/rk3328-rock64.dtb against 
the Linux version (75kb size instead 54kb size FreeBSD Version) without 
success.


Best,
C.
