Commit 03e1d93e0779 ("realtek: add driver support for routing
offload") added routing offload for IPv4, but broke IPv6 routing
completely. The routing table is empty and cannot be updated:
root@gs1900-10hp:~# ip -6 route
root@gs1900-10hp:~# ip -6 route add unreachable default
RTNETLINK answers: Invalid argument
As a side effect, this breaks opkg on IPv4 only systemts too,
since uclient-fetch fails when there are no IPv6 routes:
root@gs1900-10hp:~# uclient-fetch http://192.168.99.1
Downloading 'http://192.168.99.1'
Failed to send request: Operation not permitted
Fix by returning NOTIFY_DONE when offloading is unsupported, falling
back to default behaviour.
