Expected result:
DHCP address is accepted.
Further information:
Also tried setting the IP address manually, but there is then also no usable
LAN-connection.
E.g. ping 192.168.6.50
Result:
PING 192.168.6.50 (192.168.6.50): 56 data bytes
ping: sendto: Host is down
ping: sendto: Host is down
But 192.168.6.50 is pingable from other hosts on the same network.
On kernel releng/14.0-n265380-f9716eee8ab4-dirty everything worked fine.
