uid is the cause.  DUID was added to dhcpv4 in RFC 4361, and a dhcpd
that understands the option will treat different DUIDs as separate
devices even if they have the same MAC address.

You might want to remove "send dhcp-client-identifier = hardware;"
from your /etc/dhcp/dhclient.conf (or equivalent) on your Raspberry
