Public bug reported:
To complete the DHCP support for remote routed networks via relay agent
the dhcp agent must configure the <prefix-len> in the --dhcp-range
option. This was previously not requred becuase dnsmasq can determine it
from the local interface information. For remote networks we need to set
this property.
DNSMASQ(8)
"""
For directly connected networks (ie, networks on which the machine running
dnsmasq has an interface) the netmask is optional: dnsmasq will determine
it from the interface configuration. For networks which receive DHCP service
via a relay agent, dnsmasq cannot determine the netmask itself, so it should be
specified, otherwise dnsmasq will have to guess, based on the class (A, B or
C) of the network address. The broadcast address is always optional. It is
always allowed to have more than one dhcp-range in a single subnet.
