[Dnsmasq-discuss] Make RA_INTERVAL configureable? Deprecate old prefixes?

[Uwe Schindler]

Have fun in Berlin! But the new code makes it possible to me to set the lifetime of the dhcp-lease to good old pre-IPv6 times (86400s) so it is veeeeery unlikely that the android problem reappears. I have tested it, all is fine now.

The Android bug can be worked around by raising the lifetime/lease time in the DHCP/RA - I raised it now back to 86400 like my already existing IPv4 dhcp-range. It is very unlikely that the mobile phone is switched off to standby for longer than one day! So when it wakes up, the prefix is still valid. If the prefix changes from the provider, its correctly deprecated, so all is fine now.

One thing I found in my investigations: The lifetime given in the dhcp-range for IPv6 oly affects the RAs, but not the time for refreshing the DHCP information request. I had to set it explicitely as dhcp-option6.
