This seems to be a 100mbit switch (router), so this should be ok for the
moment.

The much bigger problem is, that the dhcp fail after warm reboot
(ctrl+alt+del). If I unplug all power and replug, the first boot of ipxe
(from usb) works fine and gets an ip-address.

It looks like some residuals in NIC firmware from ipxe which arent cleaned.
