995193ccdb odhcp6c: add workaround for broken extendprefix scenario 
Extendprefix is typically used to extend an IPv6 RA prefix from a mobile
wan link to the LAN; such scenario requires correct RA prefix settings
like the on link flag not being set.
However some mobile manufacter set the RA prefix on link flag which breaks
basic IPv6 routing.
Work around this issue by filtering out the route being equal to the
extended prefix.

8d2171e469 odhcp6c: add option "keep_ra_dnslifetime" 
Add option keep_ra_dnslifetime which will preserve the received
lifetime for RDNSS and DNSSL RA records and not overwrite it
by the RA router lifetime as specified in RFC6106.
This allows to accept RDNNS records from RAs that don't announce
a default route by setting router lifetime to 0 in the RAs.

ac7858a0f3 odhcp6c : Silence mtu write error warnings 
Silence warning "daemon.notice netifd: wan6 (1139): sh: write error: Invalid argument"
when an invalid MTU is received via RA as kernel refuses to accept IPv6 mtu values
which are smaller than 1280 and bigger than the device mtu.

8691d75917 odhcp6c: add route-workaround for broken IPv6-ISPs 
Some ISP seem to only do stateful DHCPv6 and not sending RAs.
This is technically broken because plain DHCPv6 doesn't carry routes.

We work around here by faking a default route to the DHCPv6 server
if we do not receive a useful RA from the ISP.

This workaround can be turned off with: option fakeroutes 0
