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.
