[Dnsmasq-discuss] [PATCH] Quieten DHCPv6 log when in static mode.

[Geert Stappers]

From: Ian Dall <ian at beware.dropbear.id.au>

When a DHCP range has a mode of "static" then the pool of dynamically
allocated address is configured to be of zero size. DHCPv6 will still
respond with statically defined addresses. In these cirumstances, not
allocating an address is expected behaviour and not an error, so allow
"no addresses available" messages to be quietened.
